Ending game on score count

I bought a endless fall game in asset store and am having trouble adding the function to end the game on score count. using UnityEngine; using System.Collections; public class PlayerControl : MonoBehaviour { private float i; [HideInInspector] public bool facingRight = true; // For determining which way the player is currently facing. [HideInInspector] public bool jump = false; // Condition for whether the player should jump. public GameObject BoxGUI; public GameObject PauseButton; public float moveForce = 365f; // Amount of force added to move the player left and right. public float maxSpeed = 5f; // The fastest the player can travel in the x axis. public float jumpForce = 1000f; // Amount of force added when the player jumps. public AudioClip[] taunts; // Array of clips for when the player taunts. public float tauntProbability = 50f; // Chance of a taunt happening. public float tauntDelay = 1f; // Delay for when the taunt should happen. private int tauntIndex; // The index of the taunts array indicating the most recent taunt. private Transform groundCheck; // A position marking where to check if the player is grounded. private bool grounded = false; // Whether or not the player is grounded. private Animator anim; // Reference to the player's animator component. private TrailRenderer trailrender; // [HideInInspector] public bool isDeal; // is deal ? public AudioClip[] audioClip; // public GameObject Protection; //Protection private bool isProtection; void Awake() { anim = GetComponent<Animator>(); trailrender = GetComponent<TrailRenderer> (); Protection.SetActive (false); trailrender.enabled = false; // } void Update() { // The player is grounded if a linecast to the groundcheck position hits anything on the ground layer. // grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground")); // If the jump button is pressed and the player is grounded then the player should jump. if(Input.GetButtonDown("Jump") && grounded) jump = true; } void FixedUpdate () { if(isDeal){ Destroy (gameObject.collider2D); Destroy (gameObject.rigidbody2D); Protection.SetActive (false); }else{ if(Application.isEditor || Application.isWebPlayer){ // Cache the horizontal input. float h = Input.GetAxis("Horizontal"); // print(h); // The Speed animator parameter is set to the absolute value of the horizontal input. anim.SetFloat("Speed", Mathf.Abs(h)); if(isProtection){ print ("isProtection"); if(h * rigidbody2D.velocity.x < maxSpeed) // ... add a force to the player. rigidbody2D.AddForce(Vector2.right * h * moveForce*3); }else{ if(h * rigidbody2D.velocity.x < maxSpeed) // ... add a force to the player. rigidbody2D.AddForce(Vector2.right * h * moveForce); } // If the player is changing direction (h has a different sign to velocity.x) or hasn't reached maxSpeed yet... // If the player's horizontal velocity is greater than the maxSpeed... if(Mathf.Abs(rigidbody2D.velocity.x) > maxSpeed) // ... set the player's velocity to the maxSpeed in the x axis. rigidbody2D.velocity = new Vector2(Mathf.Sign(rigidbody2D.velocity.x) * maxSpeed, rigidbody2D.velocity.y); // If the input is moving the player right and the player is facing left... if(h > 0 && !facingRight) // ... flip the player.
