Compare Target Priority and Hit Rate (00196db0)

BATTLE.BIN :  - Compare Target Priority and Hit Rate (00196db0)
Compare 2 AI action data : first AI 0x30 (?) then priority score (if equality), then Hit% 
------------------------------------------------------------------------------------------
Parameter : r4 = Pointer to AI 0x0030 (or Any other Action simulation result + 0x01c)
            r5 = Pointer to AI 0x0050
Return : r2 = 0x02 if Higher Score (AI 0x32), Higher Average Hit% (AI 0x31) or Higher AI 0x30
         r2 = 0x00 if Lower results
         r2 = 0x01 if Equality
