Consider:
myArray.sortOn( "1", Array.NUMERIC );
>From a quick test this is 2-3 times faster than the callback "compare" way.
10K entries sorted in:
sortOn(1) : 5ms
sort(compare) : 13ms
This works because array indices are considered as keys just like normal
objects.

Hello :)
you must creates benchs to test all solutions but the first is the sort()
method with a custom method
var myArray:Array = [
[20,40],
[20,10],
[30,15],
[30,35],
[40,100],
[1000,1]
];
var compare:Function = function ( a , b ) {
if ( a[1] < b[1] )
{
return -1 ;
}
else if (a[1] > b[1] )
{
return 1 ;
}
else
{
return 0 ;
}
}
trace(myArray) ;
myArray.sort( compare ) ;
trace(myArray) ;
I think the Actionscript in FP8 or FP9 really speed !
EKA+ :)
