A few things to get you going.

If $_ were
then $t_val would be 40.
Next, you need to use sort. sort operates on a list, like so:
The result is:
sort normally sorts alphabetically. To sort numerically, see the perlfunc:sort manual page.To collect all of these numbers into a list, you'll need push. Now all you need to do is put these pieces together. :)
