Can you remind me/us please? Maybe we can fix some of the details still.
I admit I can't find the discussion from last year any more,
unfortunately.
In particular the rsc_order support for resource sets doesn't just not
support score="", but also not the for/then action bits, which I think
might be extremely useful if I want to order several resources after a
master promotion; this also applies to collocation (and I also can't
collocate several resources with a node attribute).
So I think the rsc sets still need a bit of fixing.

That'd be cool. This would be much within the spirit of the CIB
representing atomic objects and management tools providing higher-level
abstraction.

Right, but I think the "order A after B; collocation B with A" is likely
the most common expression; we've got to start somewhere ;-)
