There is as Barend says there is a way a way but it does mean you need to set it up yourself. In typical use the objective scores would be based on doing A,B,C,D .... with either a fixed or weighted 'score' attached to each. That's the way that courselab handles this variable.
I can see areas where this might be useful so it's a fair question. I'm not sure if SCORM simple sequencing can change the objective rules on the fly as well as the navigation path. It needs someone to get on top of the task controller in courselab to answer that one though.
