Well, humans are basically good at learning. If you want and elf (dwarf, whatever) sage, put more points in Intelligence. By the way, why do you want to be a learned person (having many skill points) with a basically not to intelligent character? Interpret the rules as if you are not born with high Intelligence (learning ability), you are not supposed to be a sage. You can master (max out) a few (2) skills or learn and later improve the basics of other skills (not maxing 3-4 skills), but you have to focus your attention on other things to became a member of your class. If you have better learning abilities (higher intelligence stat) you can master more skills or broaden your knowledge by learning (putting skill points into) a lot more (6-8) skills.
Besides, the priest class of Pathfinder RPG is not the learned sage of the church's library, but the man of action, who defends the worshippers and takes the teachings of the god to the heathens.
On the other hand, if you wanted to play a scholar/sage type priest in my campaign, I would let you rid of the armor and shield feats for +1 skill point / level. So a priest without any armor and shield feats would have 6 skillpoints per level. Another one with ligh armor and shields would have 4 skillpoints per level. And so on.
I think the easiest way to solve these problems is to use a few house rules instead of making new classes.
