Did some scripting to make this work. For those that don't understand what that thing in the code block is, these are the results:
abjuration: 57 spells
conjuration: 166 spells
divination: 40 spells
enchantment: 15 spells
evocation: 97 spells
illusion: 7 spells
necromancy: 37 spells
transmutation: 290 spells
Hope this helps in case you want to choose school-specific caster level boosters and the like.
