I were able to reproduce that, However I have no idea why it does that. The following code seems to work as expected:

my ($one, $two) = unpack('(h2)*', 'a1');
#print "$one | $two\n";
print "found 0x13\n" if ($one =~ '13' | $two =~ '13');

But even doing this, it is splitting the two bytes into individual bytes. Is this behavior of unpack documented? I am using Active Perl version 5.16.3 as well.
