I am definitely seeing huge variations in results between .com and other other regional TLDs for the past two months (i.e. since panda was rolled out internationally). I am not sue whether it is the new order or this is because of the UE tests by google.
A friend of mine owns some very good .cctld names and they are ranking on page one for 'word cctld' (cctld in this case is a US state abbreviation). Which makes sense since the site, while simple, is for that US state. I have a feeling that Google will treat .cctld pretty much as global depending on the link origin and content. Too many extensions are beign used for US sites (.ly, .me, .la, .co etc etc)
