Rick,
Where else exactly does this string show up outside the gradebook item?
There's several strings related to the various places forum names show up. The one for "Rating grade for {forum name}" (gradeitemnameforrating) is the one for the grade items. The word "Rating" is a different string and shows up in a few other strings too as part of the phrase. So changing this would not affect those other strings.
The string in the grading item name is specific to just that one place as far as I can tell. When I grep the Moodle code, it shows me this string is only ever used once (mod/forum/lib.php line 882) : when creating / update the grade item name. It doesn't occur elsewhere in the forum itself.
