Some modifications in Wordpress template

I use a coupon theme in wordpress called couponpress. I need one change on the theme. When I publish a post we mark what kind of post is that. If an offer is a website coupon or printable coupon. When we published the post it is listed here on the individual page for each store that was selected when he was creating the post. Currently this list is in order of most recent date of posting to the earliest date of posting. What I need is that the order of the list satisfy two situations. This order: I need to show the coupon websites(first situation) in date order posted (second situation). After just below like a normal continuation of listing printable coupons put them in order of date, and then, came the offer posts in date list of the most recent to the oldest.
