Simple Example of Randomizing the order of an array in ActionScript
Just got asked this by a work mate and after asking Mr Google and looking at the Array Documentation came up with this (Flex based) example, so thought I would share :-)

private function myExample() : void
{
//can be an array of anything you like, but using letters here
var myArray : Array = ( "a,b,c,d,e,f,g,h,j,k,l" ).split(",");
//sort the array using my function
myArray.sort( myFunction );
debug.text = myArray.toString() + "\n" + debug.text;
}
//This function takes in 2 args, but we never use them...
private function myFunction( a : Object , b : Object ) : int
{
return ( Math.round( Math.random() * 10 ) - 5);// return a random value above, below or on 0 }
]]>
</mx:Script>
<mx:Button
label="Make me Random"
click="myExample();"
/>
<mx:TextArea
id = "debug"
height="100%"
