So the question arises, what stat ordering were you thinking of?
Clearly charisma is highest. But is constitution next, or strength? To melee decently at low level you need points in strength or dex. At low level str is more helpful because it boosts damage, but at high level that benefit shrinks unless you continue working at it (such as by raising your strength at level ups, and taking feats like Power Attack). Dex attacking gives you the other bonuses of AC and reflex saves, but of course it costs a feat on Weapon Finesse. (Weapons with Finesse on them do exist, but they're just not efficient in terms of enhancement bonus)
