For some reason, I thought the leading zero would address that. What was I thinking? Moving on... 

               map  { ( my $s = $_ ) =~ s/(\d+)/
                         sprintf('%010d%s', length($1), $1)
                      /eg;
                      [ $_, $s ] }
                    }

One could use pack instead of sprintf, but it won't work with unicode semantics. That's already a problem, but it'll be even worse in 5.12 because I believe unicode semantics will be used for all strings instead of just those internally encoded as UTF-8 (by default).
