Not that I know of. But you can sort any search by the number of 'voters' (people who have given that game a rating). Which should fairly closely match the order of owners.
Thanks for the quick reply. I do know about searching by the number of voters. You actually hit upon one of my questions though, which is whether or not the number of voters does in fact correlate to the number of owners? For example, I am diligent about keeping my "owned" list up to date, but I don't allow myself to rate (or "vote," in BGG speak) until I have enough plays under my belt to feel confident in my assessment. I have games that I've owned for quite a while for which I've not yet submitted a rank. I'm quite curious about the raw "owned" number. This is admittedly only to satisfy my geeky curiosity, but this is BGG after all!
