converting from GUI text to GUI Labels

I am attempting to take my project from its rough beginnings to be something that us a lot more cleaned up. Currently I am working on getting the GUI cleaned up but I am having some trouble using GUI Labels. I have 3 elements for my ingame HUD, a simple health display (that will become image based eventually), a timer and a score, the code for each is as follows.

 //healthGUI.js
 
 var healthLeft : GUIText;
 var playerStat;
 var healthStart : int;
 
 function Start(){
      playerStat = GameObject.FindWithTag("Player").GetComponent(CharacterCont);
 }
 
 function Update () {
     healthLeft.text = String.Format("{0}/3",playerStat.health);
 }

 //timerGUI.js
 
 var min : int;
 var sec : int;
 var fraction : int;
 var timecount : float;
 var starttime : float;
 var timeCounter : GUIText
 
 function Start (){
     starttime = Time.time;
 }

 function Update () {
     timecount = Time.time - starttime;
     min = (timecount/60f);
     sec = (timecount % 60f);
     fraction = ((timecount * 10) %10);
     timeCounter.text = String.Format("{0:00}:{1:00}:{2:00}",min,sec,fraction);
 }


 //highscoreGUI.js
 var currentScore : GUIText;
 var enemyTracker;
     
 function Start(){
     enemyTracker = GameObject.FindWithTag("GameController").GetComponent(enemystate);
 }
     
 function Update () {
     currentScore.text = String.Format("{0}",enemyTracker.killed);
 }

Im just wondering if there is a simple solution to this or somewhere I can read up on how to make these sort of function work in the current GUI method. I have read the tutorials on the current method but it mostly only covers static or user edited text, which doesnt help me unfortunately.
