Although I don't know as much about compter chess as you do I use a simple solution for my evaluation routine. I evaulate both sides as a positive number, but if the side is black I just negate the value at the end.
It save much programming space and time to do it that way for me.

Does it mean that you can give bonus for a pawn that is not isolated
instead of reducing the score for isolated pawns or maybe isolated pawns for white is part of the score for black?

It is possible to do things different with only positive numbers when you substract only at the end of the evaluation but I am not sure if it is more simple.
