First of all nobel prizes are offered every year. How would it occur in civ? Every 20 turns say? When would the prize be introduced? Explosives aren't in civ 3 so how about mass production? How about a minor great wonder giving a small amount of culture and rewarding you with some kudos from other civs? Don't know.
The scientific nobel prizes are awarded to innovations that have benefit to mankind. This ultimatly means that the most advanced civ would get the scientific awards, as recognised by the great scientific leaders.
Peace prize and literature prize are different matters.
Possibly a peace prize could only be introduced if diplomacy was made much more in depth, e.g. the ability to broker peace between two warring states.
Literature prize could just be a reflection of the most culturally advanced civ. No need for it.
