I am not sure what is the right approach. Ideally, code placement should be less sensitive to small changes, and we wan't to keep you honest by having a bunch of tests fail when you randomly shuffle blocks.

How about disabling it only for the metastable tests? The ones that seem to flip between equally good solutions.
