Well I would say they should be documented under perlvar because of one simple reason: They allow action at a distance, which can be one of the most perverse bugs to track down.

Consider a novice-perl maintainer. He has to modify an old module. He uses the vars $a and $b to effect some change. Unknown to him however some part of the code calls a subroutine that overwrites $a and $b. He gets weird results and cant explain them. He looks in perlvar but sees no mention. He doesnt even know that sort is being used so he doesnt know to look in perlfunc. He doesnt look at the strict documentation because like a good novice he has strict turned on already. How other by asking or by luck is he to know or figure out what the hell is going on? (Oh im assuming that as a novice he found using the debugger as imposing as I did at the start and doesnt use it, or doesnt know how at all.)

See what I mean?

But you're right that instead of submitting a bug report, I should submit a patch. Which I will do.
