I found a way to do this over the weekend. Apparently, for some components and facilities (e.g. Point Defense, Organics Generation, Life Support), the AI chooses between them based on their tech level requirements.

By listing some of the same tech requirements twice or thrice, the desirability of those components of facilities can be emphasized, without changing the actual requirements. Pretty spiffy, although it doesn't work for everything (e.g. ECM and Sensors seem to get the AI to actually look for the highest rating).
