Xcode 4 and applescript to build and run a target

Question

I am not really able to find clear info about how this should work; seems that since Xcode4 was introduced, Applescript does not work anymore with it.
All that i have to do is to launch Xcode4, open a project, select a target and build and run (to be more specific, i have a test target that runs Unit tests; that's what i am trying to launch); but so far I was unable to tell Applescript how to do this simple action.
The project is fine, it builds and runs nicely, even using xcodebuild; but it doesn't seem to work if i try via Applescript.
Is there anyone that knows how to actually tell Xcode to build a specific target with specific build settings? I am running the simulator4.0 as SDK. configuration Debug, target called "mytestsuite".
So far I can only launch and load the project into Xcode, but any other option fails, like when i tell the project that i want to build.
Any help is more than appreciated; the lack of resources honestly is making me think to abandon Applescript for something that has more examples and is much more user friendly...but for now I gotta use it so can't avoid to deal with it (can't use xcodebuild sadly).
Thanks in advance for any info.

No worries; my nick is pretty common among people that likes Japanese animation (is the nick of the main protagonist of a series called *******!!! that was pretty popular in the 90s); the only place where i use it is mainly here or on pelicanparts and classicamiga.
Anyway surprise me that nobody use applescript to build Xcode4 projects; probably everyone uses either xcode3 or just use xcodebuild.
