I'm trying to figure out how to do an Excel type sort in Perl but
can't seem to find anything on specifically what I want to do. So here
goes.

Imagine 3 columns of numbers: A, B, C.

I want to sort in descending order starting with Column A then Column
B, and then Column C.

Thing is I don't want the order of A to change when sorting B and i
don't want the order of A or B to change when sorting C.

I have no idea if the way to do this is with arrays or hashes.
