AI Research Queues

[Devnullicus]

OK, I'm working on modifying the UkraTal as a test case for using a new technology tree (see the "devnullmod" thread for more details) and I'm having some serious confusion issues with the way the AI does it's research queue.

Here's what's happening: I have the AI_Research file set up below. With that, I start a game with low tech costs and high starting values. But the AI seems to ignore many sections of the AI_Research file and skip ahead to future research for no apparent reason. So, the first turn, the UkraTal research
-Ship Construction 2
-Organic Engineering
(so far, so good)
-External Mount Missile Weapons 1
(HUH??? What happened to Organic Weapons 1??)

In the queue at the beginning of the next turn is Military Science 1 (thus skipping Organic Weapons 1, Ship Construction 3, and Missile Weapons 1)

I'm VERY confused as to why the AI seems to skip researching some technology. Does anyone know what's wrong? Am I doing something wrong?

Here's the relevant bit of UkraTal_AI_Research.txt
