I apologize, I did not have time to respond at the time I first saw your post or when you bumped it, and then it slipped my mind to reply later on.
So, first, let me point you to an example of how to use #morality[] in a script.
On the ability tab, make a copy of "Low Clarity", and take a look at the eval script there - see how #morality[] is just used as a reference for a number in that script?
Okay, so for the script, you're going to select Effects as the phase, and 10000 as the priority. I'm afraid I can't find a good example to show you, but that should work.
The calculated roll is stored in a field called rcalcpool - "roll's calculated pool", and you want to add the value of morality to everything else in that pool:
Code:
field[rcalcpool].value += #morality[]
