Well, it sounds like that should work (you checked the setting for "Allow Users to have Member Groups", right?). But if the "solved" thing is a mod then it could be it only checks for the main usergroup.

I tried it on my test system and adding Super Moderator as an additional group definitely allows the user to edit posts.

If you're trying to add super moderator permissions without making the user look like one, you might be able to do it by setting their primary group to Super Moderator then setting a "Display Usergroup" (edit the user, it's a dropdown under the main usergroup). But to be honest I'm not sure if that completely hides the fact that they aren't a normal user.

The only infomation I know of is the online manual, it's at vbulletin.com under the support menu.

Edit: there's a link to the online manual under "Quick Links" on this forum. Also, if you go there remember to select your vbulletin version from the dropdown menu on the left before you start to read.
