Hello Ernest, I just wanted to thank you once again for the really valuable help, and let you know that it works now :)
Currently, I'm using second approach - asserting (tried-to-create-counts) fact for a group of counts.

I'm going to try modules approach recommended by you anyway, I figured I will need it in another application.
