variables reset value

Hi all!
I am making a old school pong game, and I am quite stuck now. i have made that when player01 scores 10 points, a new scene will show up, saying that this team has won. But if you return to the Main Menu by clicking a button, and play the game again, the score won’t reset. Can someone please help me out?
Here are the scripts I use:

//for the score

#pragma strict

static var playerScore01 : int = 0;
static var playerScore02 : int = 0;

var theSkin : GUISkin;

var theBall : Transform;

function Start () {
	theBall = GameObject.FindGameObjectWithTag ("Ball").transform;
}

static function Score (wallName : String) {
	if (wallName == "rightWall")
	{
		playerScore01 += 1;
	}
	else {
		playerScore02 += 1;
	}
		if (playerScore01 == 10) {
			Application.LoadLevel("OrangeWins");
			Debug.Log("OrangeWins");
		}
		if (playerScore02 == 10) {
			Application.LoadLevel("OrangeWins");
			Debug.Log("PurpleWins");
		
		}
		if (Application.LoadLevel == true) {
			playerScore01 = 0;
			playerScore02 = 0;
		}
	Debug.Log("Player Score 1 is" + playerScore01);
	Debug.Log("Player Score 2 is" + playerScore02);
	
		
		
}

function OnGUI () {
	GUI.skin = theSkin;
	GUI.Label ( new Rect (Screen.width/2-150-18, 20, 100, 100), "" + playerScore01);
	GUI.Label ( new Rect (Screen.width/2+150-18, 20, 100, 100), "" + playerScore02);
	
//	if (GUI.Button ( new Rect (Screen.width/2-121/2, 35, 121, 53), "RESET")) {
//		playerScore01 = 0;
//		playerScore02 = 0;
		
//		theBall.gameObject.SendMessage ("ResetBall");
//	}
		
}
 //for the camera
#pragma strict

var mainCam : Camera;

var topWall : BoxCollider2D;
var bottomWall : BoxCollider2D;
var leftWall : BoxCollider2D;
var rightWall : BoxCollider2D;

var Player01 : Transform;
var Player02 : Transform;

function Start () {

	//move each wallto its edge location:
	topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f ,0f)).x,1f);
	topWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3 (0f, Screen.height, 0f)).y + 0.5f);
	
	bottomWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f ,0f)).x,1f);
	bottomWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3( 0f, 0f, 0f)).y -0.5f);
	
	leftWall.size = new Vector2(1f, mainCam.ScreenToWorldPoint(new Vector3(0f, Screen.height*2f, 0f)).y);;
	leftWall.center = new Vector2(mainCam.ScreenToWorldPoint(new Vector3(0f, 0f, 0f)).x - 0.5f, 0f);
	
	rightWall.size = new Vector2(1f, mainCam.ScreenToWorldPoint(new Vector3(0f, Screen.height*2f, 0f)).y);
	rightWall.center = new Vector2(mainCam.ScreenToWorldPoint(new Vector3(Screen.width, 0f, 0f)).x + 0.5f, 0f);
	
	Player01.position.x = mainCam.ScreenToWorldPoint (new Vector3 (75f, 0f, 0f)).x;
	Player02.position.x = mainCam.ScreenToWorldPoint (new Vector3 (Screen.width -75f, 0f, 0f)).x;
}

//for the ball
#pragma strict

var ballSpeed : float = 100;

function Start () {
	yield WaitForSeconds (2);
	GoBall();

function Update () {
	var xVel : float = rigidbody2D.velocity.x;
	if (xVel < 18 && xVel > -18 && xVel !=0) {
		if (xVel > 0) {
			rigidbody2D.velocity.x = 20;
		}
		else {
			rigidbody2D.velocity.x = -20;
		}
		Debug.Log ("Velocity Before " + xVel);
		Debug.Log ("Velocity After " + rigidbody2D.velocity.x);
	}
}

function OnCollisionEnter2D (colInfo : Collision2D) {
	if (colInfo.collider.tag == "Player")	{
		rigidbody2D.velocity.y = rigidbody2D.velocity.y/2 + colInfo.collider.rigidbody2D.velocity.y/3;
		audio.pitch = Random.Range(0.8f, 1.2f);
		audio.Play();
	}
}

function ResetBall () {
	rigidbody2D.velocity.y = 0;
	rigidbody2D.velocity.x = 0;
	
	transform.position.x = 0;
	transform.position.y = 0;

	GoBall();
}

function GoBall () {
	var randomNumber = Random.Range(0, 2);
	if (randomNumber <=0.5) {
		rigidbody2D.AddForce (new Vector2 (ballSpeed, 10));
	}
	else {
		rigidbody2D.AddForce (new Vector2 (-ballSpeed, -10));
	}
}

//for the Back buttons in the menu.

    var levelToLoad : String;
    var soundhover : AudioClip;
    var beep : AudioClip;
    var QuitButton : boolean = false;
    function OnMouseEnter(){
    audio.PlayOneShot(soundhover);
    }
    function OnMouseUp(){
    audio.PlayOneShot(beep);
    yield new WaitForSeconds(0.35);
    if(QuitButton){
    Application.Quit();
    }
    else{
    Application.loadLevel("pong");
    }
    }
    @script RequireComponent(AudioSource)




//Application.loadlevel("LevelToLoad");    **DOES NOT WORK**

Thanks for the Help!!

Just place playerScore01 = 0 and playerScore02 = 0 on your score file in both positions 22 and 26 and scrap the if(Application.LoadLevel) on line 31 to 34

static var playerScore01 : int = 0;
static var playerScore02 : int = 0;

Do you know what static means?
