That's why he broke it down. Is the map() really the problem, or is it
the regex, the ?: operator, and the two array references?

I'm not sure I understand YOU. Did you mean "... why there is COMMA
between THE SORT logic and @data here:"? That makes more sense.
The reason there's no comma is because Perl's grammar says you don't put
commas after blocks like that.
map BLOCK LIST
grep BLOCK LIST
sort BLOCK LIST
cf.:
map EXPR, LIST
grep EXPR, LIST
