This dont work like that.
First: MOZ spam score is a metric used by MOZ only, meaning it's apart from Google or anything else. So far i understood was that MOZ uses 27 different metrics to calculate a spam score. Apart from that it does'nt do anything in relation with google.
You wrote that you put them all in disavow, why? Are your ranks hurting because of it? You know that entering these in Disavow wont do anything for MOZ DA/PA calculation right? As it's complete different products your using and doing now.
Disavow should only be used when, you have or see potential hurting links to your website that you do not control.
