Sorry for late reply.
There is a Condition Check CSharp Event under Script Control. With this you can subscribe to an event and the condition will return true when it is raised.
Alternatively you could manualy call SendEvent(string) from your mono behaviour if you have a reference of the BehaviourTreeOwner (FSMOwner) or the Graph itself, and then check that even as normal with the Check Event condition.
