Can I keep adding to the byPhone sub? $c, $d etc?

While sorting, $a and $b (and only those two) are special. They've been localized, and hold the two items being compared for sorting purposes. All is explained in perlfunc in the section on sort.

Since you started with the ActiveState distribution, you'll have all of the core Perl docs available via Start | Applications | ActiveState Perl.
