Priority ? Bug ?

[Garylau]

How do I make my kodo (AI unit ) focus on attacking the wall built by player ? When a player build tower , the tower attack the kodo and the kodo "forget" their mission and wanna attack the tower which attack them .But course the wall is blocking them so they just walk from X point to Y point and rewalk. Now , all the priority of the tower I've set is 0 and wall is 20 (first attack) and the attack type of kodo is nearby attack but still happen the problem I say just now . How i fix it ?
Check out my latest map if wonder what I'm say .

errr......as far as I know, "priority" only affects selection. When a unit's priority is high, he's the first one (most top and left) selected in the unit command bar.
