project-specific releases page needs sorting options

once the new release system goes live, and releases are real nodes (http://drupal.org/node/83339), the existing "view all releases" page is going to start to get quite huge and unwieldy. in addition to being able to filter on core compatibility (http://drupal.org/node/89535) it'd be nice to add a way to sort based on various things (like the project browsing pages):

1. date (current default)
2. core compatibility
3. a release "series" (e.g. a specific stable or devel branch for a given core API).

should these be tabs?
should #2 and #3 be merged?
any other sorting/grouping options we'd want?

mockups, screenshots and patches welcome.
