A lot of the logic can be seen around here as to why a mob will attack:

Alot of this boils down to faction and kamikazee tactics. Orcs are well known not to be very bright.
Couple of rules noted:
RULE_INT(Aggro, MinAggroLevel, 18 ) // For use with UseLevelAggro
RULE_BOOL(Aggro, UseLevelAggro, true) // MinAggroLevel rule value+ and Undead will aggro regardless of level difference. (this will disabled Rule:IntAggroThreshold if set to true)
lowering 18 to something smaller should alter behavior.
