ATM constraint match needs to be specified in the Guided rule editor (GRE) manually, e.g.

scoreHolder.addHardConstraintMatch(kcontext, - (1 + l.getCourse().getCurriculumList().size()));

It's important the user doesn't have to specify the scoreHolder global variable anywhere. This should be ideally performed behind the scenes, based on the selected score type in PlannerDataObjectEditor (see solution_type.png). In the first iteration investigate the possibility to generate a .drl file containing the definition of the scoreHolder each time the score type changes.
