PlayerPrefs after 0 lives, want to load another scene.

I want to load another scene when player got kill when is > 0. I don't want to load on 0, I want to load when is played with 0 and is killed. I think the problema is in "Public void zeroVidas ()"

How can I do it? There's my script.

 using UnityEngine;
 using System.Collections;
 
 public class VidaScript : MonoBehaviour {
 
     //Interfaz Grafica Vida
     
     public int vida = 0;
     private static int vidasIniciales = 2;
     private static int vidasActuales;
     public GUIText LivesText;
 
     //Prueba
 
 
     static VidaScript ()
     {
         vidasActuales = PlayerPrefs.GetInt("lives", vidasIniciales);
     }
 
     public static int VidasActuales {
                 get { return vidasActuales; }
                 set {
                         vidasActuales = Mathf.Max (0, value); // Para que no de negativo.
                         PlayerPrefs.SetInt ("lives", vidasActuales);
                 }
         }
 
     void Start () 
     
     {
         vidasActuales = PlayerPrefs.GetInt("lives", vidasIniciales);
         UpdateVida ();
 
     }
 
 
 
     public void Subtract (int newValueVida)
     {
         vida -= newValueVida;
         UpdateVida ();
 
 
     }
     void UpdateVida ()
     {
         
         LivesText.text = "Lives: " + vidasActuales.ToString ();
     }
 
     public void drecrementoVidas ()
     {
                 vidasActuales--;
         PlayerPrefs.SetInt("lives", vidasActuales);
 
         }
     public void incrementoVidas ()
     {
                 vidasActuales++;
         PlayerPrefs.SetInt("lives", vidasActuales);
 
         }
     public void zeroVidas()
     {
                 if (VidaScript.vidasActuales > 0)
                         Application.LoadLevel ("StartScene");
     }
 }
 

Thanks for the help!
