Minor thoughts

[Manzo_]

-if an army is getting big attrition, its morale should be lower, particularly if they are getting it during a siege that has lasted for a long time.

-if the wargoal is a province that doesn't have a fort, the warscore shouldn't increase constantly over time, but it should start increasing only when the closest fort has been conquered.

Good points, I agree.

Agree on the first suggestion.
Disagree on the second because it is your wargoal, the reason you started it so once you capture the province, altough you cannot ask it without controling any forts, it's still the most important objective for your troops, your nation.
