The question about awards has been raised many times before. At some point there were quite realistic plans for it too. However, every time the idea has crashed to the complexity of arranging it and the simple need to focus the few resources OFPEC has. In other words, there's not enough resource to pull it off, in any classy way anyhow.
As Roach said above your cheap substitude is to consider the ratings as awards. Also earning the 'OFPEC approved'-stamp on your mission is the mother of all awards. 0/10 could be the award of the worst mission.
I think rating scripts is a no can do at the moment.
A mentioning on the main page news could be a nice and simple solution to run this awards idea. I think everyone submitting stuff to OFPEC would be thrilled to see his work mentioned on the front page.
I don't speak for the OFPEC administration, so don't quote me in anything
