The easiest would probably to use http://nz.php.net/manual/en/function.strnatcmp.php . It would happen to sort it the right way because am is before pm ;-). You can of course make it more challenging by converting it into a timestamp etc. That would be better if you want to sort by date as well etc. If you go that way you should look at http://nz.php.net/manual/en/function.usort.php .
