In the new api (developer.vimeo.com/api) play stats are included in each clip response.
So if you made an HTTP GET request to /me/albums/[album_id]/videos, you should be able to loop through the videos (and through multiple pages if necessary) and pull out the play data.
We don't expose much more than the play data yet, but there will soon be Advanced Stats exposed through the API, just like on site.
