Turn on verifyUndoMoveIsUncorrupted, see
   https://jira.jboss.org/jira/browse/JBRULES-2391

Score rules shouldn't modify the facts.
They should only change the ConstraintOccurrence's and the scoreCalculator.

The doMove method can change the facts, but the undoMove method should 
undo all those changes.

Change = add, modify and/or delete
