Custom Softaculous Script w/Auto-Install on Order

I need a custom script created in Softaculous that will auto-install when an order is placed in WHMCS for a particular package. It's not a complicated package, it's WordPress + 3 plugins and 2 themes. I also need the license codes for 2 plugins pre-populated on install.

This will take some troubleshooting as I can't get any auto-installs to trigger in WHMCS up on order, even the basic WordPress installation.
