Of the three attributes you have defined I think that the highest possible set of ratings I would give is -
Power - Omnipotent
Intelligence - Omniscient
Benevolence - Neutral
An omniscient and omnipotent God could, from our perspective, have done a much better job but if benevolently neutral had no reason to do so.
Thus the struggle for life and the inherent reliance of nature on pain, death and suffering are just the products of this indifference and neutrality as much as are the concepts of good, beauty, love etc. etc. etc. Maybe the mix makes sense if we consider that the God in question seeks the most entertaining end result from his perspective with little care for our perspective at all.
If a neutral God looking down at us, much as we might watch an ant colony, is seeking something worth watching then maybe the current mix is just the most conducive to that.
But I think omnipotent, omniscient and indifferently neutral provides the highest total consistent combination from the choices you have given.
