Be sure you have the "Already Built" box selected for the AI command Center on the Build List. Also Everything in a mission needs to be scripted INCLUDING giving the player cash so they have money to build and setting the build permissions, allowing them to build units and buildings. If these are set, the AI should build from the build list. Make sure the build list is in order so they build power (if needed) then a supply center before going to other buildings.
