There have been reports recently (from jpugh, davmor2 and a dev) of for-purchase apps not displaying in Software Center (the most recent being https://apps.ubuntu.com/cat/applications/oneiric/nanoparticles/ ).
Apparently it was discussed recently (I wasn't involved) and diagnosed as some type of cache issue, but I'll let those in the know update this description with something more useful.
