Well, we can have layering (layer=-5 ... 5) like for any other tags, so we could have small zone with different limits within one large zone. For clashes with "default" rules from place=... and alike, we can define some rules of precedence (speed limits on individual ways have highest priority, followed by rules from speed limit zones, rules from place=..., then default country rules). And if zones with same priority overlap? Then it is bad mapping (as are typos like highway=residental or other bugs) and someone needs to fix it in the database.
