I don't think the ordinal scale is a problem (you can use it in many types of analysis - logit or probit, even a usual regression). The problem is, it's not clear, how you want to formulate the problem. Does MIP have a better diagnostic value than MPR? Probably you can do a paired test then.
Sorry, I wish I could be more helpful.

My friends continuously question me why my husband did no longer supply me a diamond ring I have been given married, and that i say to them, i do no longer desire a bite of rock to coach to me that i'm married. the main efficient issues in my life are my lovable nieces and nephews and that they are efficient.
