The idea is sound. Depending on how many duplicates there are, it may end up more expensive (since you're sorting the entire array, instead of only the unique items). Also, the line @array = (sort shift @sorted) is really...odd. Why not just @array = shift @sorted? Additionally, I think instead of while (my $element = shift @sorted) { I would have just used for (@sorted){, unless there's a reason you really want to destroy the sorted version as you go.
