A few things:
1) There is a ACS 4.x TCL Package Porting page at
http://developer.arsdigita.com/acs40-project-central/porting-schedule.html. It is mostly up-to-date with the latest releases.
2) The majority of the ACS 4.x TCL packages have not gone through a central QA test, so there is no ranking of the "quality" of each package. (flashbacks to zen and the art of motorcycle maintenance...) However, almost all packages have been code-reveiwed and gone through some testing.
3) The "d" extension to version names indicates development release, which may or may not be usable.
4) If you find bugs when beating on the pakages, please post them at
http://www.arsdigita.com/sdm/.
