I doubt it. A credit score is a good implementation of your material value to capitalism. If you have a bad credit score, you are punished exactly to the extent it makes sense from a statistical perspective.

'Social credit scores' muddy this system with a bunch of basically peripheral values: filial piety, political opinions, and so on. It undermines the basic efficiency of a system that only cares about you insofar as you matter - i.e. insofar as you're economically active.

The only way a 'social credit score' will help the system that institutes it is if the society is more stable as a result. I don't really see this happening, unless people like it. If everybody hates a society, you tend to get a kind of creeping malaise, where nobody believes in the system, and everybody's just trying to steal as much as they can from it - sort of like Russia in the 80's. No amount of repression will help you if all of your secret police are busy trying to sell every state asset they can get their hands on.
