Can a scripter make a script involving arrays?

This is pretty hard to explain so please bear with me.

I would like an array type based quest that operate like the radiant story quests in Skyrim.

Radiant quests like the Bandit Chief quests.

I wanted to make a quest that is the Oblivion equivalent to Skyrims radiant quests that use aliases.

I could just drop an NPC in the game world with a script on it but I think that it would be more fun for the player make use of the random bosses already in the game. Besides I rather avoid scripting NPCs that may conflict with other mods.
