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;
