How about a compromise - not a score for each policy but for "each" individual, or tranche of similarly concerned individuals. I go through a list of privacy options (maybe just once) and the point at which my "okay" becomes "not okay" determines my score. Then each policy simply passes or fails based on my score. And if you want more detail, the list of failure items for a given policy can be bulleted.

Or make the rank adjustable to some personal criteria that matches different privacy expectations.

This would also be helpful in determining how to weight (or not) user feedback in the training portion. I just tried it out (the 10 questions) and there were at least a few I thought, "huh, I know some others would disagree with me on this" because I value X and they value Y more.

Having scores that weight X more than Y would give me more accurate scores, while seemingly also giving other people more accurate scores at the same time.

A good compromise would be a chrome extension that shows a 1-10 score. You click the extension to see clauses

Not for everyone, as thecleaner pointed out. You are assuming your requirements are universal among other users. Also, you are assuming the policies can be simplified to a weighted average of their parts, which is not necessarily the case.
