Casey,
I agree with AKing. Keep asking. This is why we have confessions. My own children can read WCF 19:2 and see that "and, as such," is modifying "a perfect rule of righeousness".

And like you have said, simply reading on in the confession we find that for the church, the ten commandments are not to be used as a covenant of works. 19:6“The promises of it, in like manner, show them God's approbation of obedience, and what blessings they may expect upon the performance thereof;(s) although not as due to them by the law, as a covenant of works

Keep up the good work. I don't know where this error is going but the consequences could be huge. Next they will be redefining what a covenant of works is, or maybe they already have.
