Actually, PFS does not change the rules on this. You can indeed take 10 on Spellcraft checks. For 99% of wizards/witches/magi/alchemists/etc., this means you automatically succeed on the check to learn new spells, so long as you declare that you are taking 10.
The corner case would be something like a fighter with 11 Int dipping wizard for true strike or something.
