I managed to fix my callback issue.
I think it has something to do with the fact that I'm running the WPOSC version of OSCommerce. So I'm not sure what code was causing the problem but if anyone else is using WP OSCommerce for Wordpress then perhaps they'll find it useful.
This is the complete code I used in
catalog/ext/modules/payment/worldpay/junior_callback.php
