Shuffle a Vector in ActionScript 3

During a Project i needed a method which shuffles a Vector. Since i could not find an implemented shuffle() function i remembered how PHP works with sort-functions and came up with this really simple comparison function:

package de.patricktresp.util
{
	/**
	 * @author patricktresp
	 */
	public class VectorUtil
	{
		public static function shuffleVector( a : Object, b : Object ) : int
		{
			// HIDE FDT WARNINGS
			a;
			b;
 
			return Math.floor( Math.random() * 3 - 1 );
		}
	}
}

So whenever needed i just go:

vector.sort( VectorUtil.shuffleVector );

This works fine for now, but i am very sure there is some more efficient and faster methods.

Suggestions are appreciated.
