If you have the exact same Action in both Permission and Prohibition, then the Perm will win out.
But in your case, the Action in the Prohibition is further constrained (hence, not the same) so there is actually no conflict to trigger.

Suppose that a Policy contains some permissions and prohibitions where the intended resolution of conflicts is to prohibit, whereas there are other permissions and prohibitions where the intended resolution of conflicts is to permit. Would such cases be inexpressible in ODRL? Or would one simply attach multiple Policies to the asset in question?

I think multiple Policies is the safest way...
