That's the same problem I ran into on the first page. I'll quote to save you the trouble of going back:

However, GetObjectByTag does recognize 0, and inputting 0 doesn't immediately crash the game. So there's that.

And the essential code:

		if( GetIsObjectValid(oCreature1) ){
			ChangeToStandardFaction(oCreature1, iFaction);
			DelayCommand(1.0, AssignCommand(oCreature1, ActionAttack(GetNearestCreature(CREATURE_TYPE_REPUTATION, REPUTATION_TYPE_ENEMY, oCreature1, 1, -1, -1, -1, -1 ), 0)));
			}
		else break;
		}

So something like this should work:

	sTag = "d50ab_sitter";
	int i = 1;

	for(;;) {
		i++;
		object oPlaceable = GetNearestObjectByTag(sTag, OBJECT_SELF, i);
		if( GetIsObjectValid(oPlaceable) ){
			AssignCommand(oPlaceable,ActionPlayAnimation(ANIMATION_PLACEABLE_ANIMLOOP01));
			}
		else break;
		}

You might have to fiddle with it a bit. I can't remember all of the details.
