Where does it go wrong? Do those cases come up in practice?

Counting up and down the scale is a core use case for a notation for intervals. It absolutely needs to be well-supported. A 12-semitone approach is never going to match the usability of even the existing system.

I am obliged to point out that a 12-semitone approach is in fact part of the "existing system" (see: pitch-class set theory).

(Mind you, I of course think its usefulness is overrated, because I think the "atonal" repertory is tonal.)
