johnward, I know of at least one other SEO that has been doing a more rigorous study of whether more +1s lead to a higher ranking. I suspect that study might come out in the next month or two.
Suffice it to say that I would be very skeptical of anyone who claimed that more +1s led to a higher search ranking in Google's web results.
