Consider using an Array literal:
var tabs = ["one","two","three","four","five"];

Prototype.js extends the built-in Array object's methods, a for..in
loop will return those methods too. Use a normal for loop:
var target;
for (var i=0, len=tabs.length; i<len; i++){
target = document.getElementById(tabs[x]);

You can replace all that with:
target.style.backgroudColor = (tabs[x]==chosen)?'white':'#E7F1F8';
Though you might try Prototype.js's Array.prototype.each() method.
