You're going to get the ability to get the same result in either fashion. However, for my reply to a similar question on array sorting, merlyn pointed out that the ST is overly heavy for the sorting, and the method that I suggested above was better for getting the sorted indices. Now, with mine, you can rebuild the sorted array via the map I provided, but it's just as easy to do this as well:

@sorted_indices = sort {...} (0..$#array); # as above
@sorted_array = map { $array[$_] } @sorted_indices;  #as above
my @to_position;
$to_position[ sorted_indices[ $_ ] ] = $_ foreach (0..$#array);  # thi
+s is new

IMO, I believe this is more lightweight and a bit easier to follow for the given code than using the heavier ST for the same. Not that the ST can't be useful in a similar situation if the comparison values are heavy in terms of calculation times, but here they defintely aren't.

It's not what you know, but knowing how to find it if you don't know that's important
