Science Victory: Freedom or Order?

I'm afraid the code gives a strong incentive for the second to reach ideology to pick something different.
The main thing you can do for those 3rd to an ideology if you are first or second is to have him like you more than he does that other civ.
As a proxy, you can probably assume the AI with the most techs (without an ideology already) is the most likely candidate to next reach an ideology.

There are other factors that you can't really control. There's no way to tell when an AI is in the industrial era which victory condition he is seeking, so you don't know if he's ruled out Order (via wanting Diplomatic victory) or ruled out Freedom (via wanting Domination victory)

Yeah, a tall core empire that's attached a wide empire has advantages in both ideologies. Again the tall cities will benefit the most from Freedom (run every specialist possible while continuing to work every useful tile & all great improvements will definitely be these cities as well) while the smaller cities provided they have enough food already will benefit the most from Order.
Freedom appears somewhat more flexible as it will also allow a city struggling to support its scientists to grow while Order's factory bonus requires you to have gotten coal from some source, which in some games is hard to find.

That's a clever way of doing it, but really, I've found recently that I like to bite the bullet and start my own ideology. I realize that I'll probably lose it if I can't force the WC or UN down their throats or be a cultural powerhouse, but really, you only lose two tenets, so it's about a wash compared to if you went with one that already had two followers. Starting up your own lets you grab up any tenets that had any one time effects, and get the wonder that associates with the ideology. An exception might be if I'm trying to go domination, and Autocracy is the hot ideology. It's built through and through for domination, but it's hard to keep ordinarily because the popular ideology is determined by cultural influence.
