"the equal or less than" works decently enough, but it does have problems with Ai defense when u have "2" building type's
Lets say u create a Sov bunker fill team, the first one with house own's "1" bunker works flawless, However....when U have a second Trigger Stating Equal to "2" bunkers the AI will build that team and another until the bunker is filled......
It seems when u have "equal to" (2 or more buildings) as AI defense which deploys/ enters structures the AI will build the team twice...and in your case the Artillery deploys, then the second team it builds deploys<--  this is not counted as a seperate trigger, just the same trigger so it goes on and on
the same goes with the enter bunker teams, it will constantly build the Team and send it to the bunker until the bunker is filled, if the Bunker is built far away from the Barracks, the AI will build a endless stream of unit's until that bunker is filled.....This however stops once the bunker is filled, but the team itself is only counted when it exist on the field, not in the bunker so really u must have 5 conscripts outside the bunker not following script to stop the building of the units
(it doesnt follow the equal to X number of buildings at all for any cut off it's used only for the creation of a trigger)
.....Since your Unit's are deployed/ following script, it constantly tries to replace itself, same thing happens with Miners, since the Miner begins working it is not counted as on "field" because it is following script, mining, or what eva. The AI will build and build until it has one miner not doing nothing then and only then will it stop production of the miner
Try and try again is all I can say
It's really hard designing let alone figuring out this AI, take for example I just found out recently u can change the order of the building list (In rules.ini) all the way around any way u like it, just u have to create a AI.ini file from scratch (everything must be erased except for digest) otherwise u will break your game.... Dcoders AI editor doesnt erase sometimes so u have to do it manually
BTW:  Final Alert 2  does not read the building list from a internal table as Deezire's guide states it reads it from the rules.ini file
