I don't know enough of the specifics of yahoo's scoring.
However, in my experience it is better to have your sending host IP have a resolvable PTR record than not. I'm quickly loosing track of this thread, but it appears bobhoffman.com has that covered.
As an aside, it would be my expectation that forward/reverse DNS literal matching wouldn't be scored highly (if at all) simply due to the common use of virtual hosting and the like, let alone the split in/out mail architecture already discussed.
