Not disagreeing with the strategy, however if there is a large quantity of data, shouldn't you restrict the sort element of the array to contain only the element to be sorted, as far as I can see it adds no overhead (we already have a list from the split function) and reduces the memory usage. ie
#!/usr/local/bin/perl
use strict;
use warnings;

my @data =
    ('AC-BA91-CA', 'AB-BA92-CA', 'AD-BA90-CC', 'AA-BA93-CA', 'AA-BA89-
+CB');

my @sorted =
    map {$_->[0]} sort {$a->[1] cmp $b->[1]} map {[ $_ , (split '-')[1
+] ]} @data;

print "$_\n" for @sorted;

Just wondering, Utilitarian.

print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."
