sort doesn't sort a list in-place. Instead, it returns a new sorted list. So:
foreach (sort @$outputRef) { print $_, "\n"; }
would print out a sorted list, but printing the contents of $outputRef would still print out an unsorted list.

If you need to save the sorted list for some reason, use an assignment:

@sorted = sort @$outputRef;
