can I compare a packed MAC just as I can compare it after unpacked?

Yes. Before you unpack and format them, your octet strings are just sequences of bytes with binary values in the range 0 -> 255. Ie. strings. Perl's normal string comparison operations (eq, ne, lt, le, gt, ge) will work perfectly on them; and you can use cmp to sort them.
