Did you try the above? I think BTest *will* run before ATest. The sorting is 
performed by the TestLoader if there is one, i. e. if you don't build a test 
suite manually. If you *do* use a TestLoader you can still influence the 
sort order by defining a sortTestMethodsUsing static method. Here's a fairly 
complex example:
