Sort CustomPress CPT by custm field(like categories)

I want to sort archives of my CPTs based on a radio button custom field in CustomPress. I would love it if my users could just check a box for "Job Type" without necessity to select category in addition.

I want it to basically work like categories, but without categories. I have unlocked WPMU access to my site if a closer look is in order.

The site in question is hro.minationalguard.com(/jobs). It is my "Jobs" CPT.
