Wow, that's a nice node that I wasn't previously aware of. The basic shortenings I made were:

• all variable names one char in length
• eliminate variables where you can
• removed quotes from strings (e.g. "FRED" -> FRED)
• $x=1;$y=1 -> $x=$y=1
• shift -> pop in subs
• removed return in subs
• split // -> /./g
• for {...} -> ... for
• if {...} -> ... or ...
• ' ' -> $"

These all seem to be mentioned in Perl Golf 101, except perhaps the last one. BTW, I've added Perl Golf 101 to the list of references in The Lighter Side of Perl Culture (Part IV): Golf.
