Good point. Let's try this then:

~ Assign the appropriate tag to all weapons that meet the criteria
  foreach pick in hero where "WepFocus.? & (thingid.wBattleaxe | thingid.wWarhammer | thingid.wGreatclub)"
        perform eachpick.delete[wCritMult.?]
    if (eachpick.tagis[thingid.wGreatclub] <> 0) then
        perform eachpick.assign[wCritMult.3]
    endif
    if (eachpick.tagis[thingid.wBattleaxe] + eachpick.tagis[thingid.wWarhammer] <> 0) then
        perform eachpick.assign[wCritMult.4]
    endif

PS Just tested this. Seems to work.
