Well, Valencia (or an extra settler) will make it back in at some point.
As for House of Wisdom. It seemed (from a couple test games) that the AI just avoided Education, and because it's not really required for any military techs they were able to do just fine and hold off the Spanish attack.
So the way I have it now, you can become quite technologically advanced as Cordoba, but only at the expense of your military. This still isn't resulting in Spain taking over Cordoba at all regularly, so...
Perhaps a better option would be to keep the obsolescence at Education, but make Education required for some key (defensive) military units.
Or maybe just stop trying so hard to make Spain take over Cordoba. As you have it now neither can get the upper hand very easily. Although I've done it once myself as Spain at the expense of other UHV goals. Which does make the other UHVs for both of them pretty pointless now, doesn't it?
