There is probably misunderstanding. The problem is what attribute is
used, not how it is set.  crmsh sets (and as far as I can tell always
set) attribute with name fail-count-<resource> while pacemaker
internally sets and queries attributes with name
fail-count-<resource>#<operation>.

It is possible that this has changed in recent pacemaker versions of
course ... yep, here is crm_failcount commit that implemented new
(per-operation) failcounts. Which means "crm resource failcount set"
without qualifying by operation is simply not valid ... actually
crm_failcount will refuse to set failcount at all (only clear it).
