I suggesr try replacing your second rule expression to simply the word true, lowercase and no hyphens.

It will require that you create a programRuleVariable for each data element that is going to be scored, and make rules that calculates intermediary scores - one for each data element to be scored. Then after the intermediary scores is assigned, you can sum the whole form.

I have created a program rule expression where if an option is selected and then the rule action to increment the value for the score data element using the assign value function. This is done for different fields across the program stage. But when any option is selected the score variable increases. I'm using 2.27 of DHIS2.
