A solution using List::MoreUtils.
Isn't the most efficient since it doesn't shortcut the comparing of array elements. Also duplicates the use of localized $a and $b, but overall I think this is very readable.
use List::MoreUtils qw(lastval pairwise);
my @array = (
['blah', 'asdf', 'foo', 'bar'],
['two'],
['zzz', 'def', 'ghi'],
['one'],
['mmm', 'def', 'ghi'],
['qqq', 'xyz', 'aaa'],
);
@array = sort {@$a <=> @$b or lastval {$_} pairwise {$a cmp $b} @$a, @
+$b} @array;
use Data::Dump;
dd \@array;
