How did you ensure that your goal only initialises after the RegionStarted("TUT_Tutorial_A") event?
If you run your mod in the editor, you can have a look at the file osirislog.log (in the same directory as the editor binary) after starting game mode. If you then search for "DB_Dialogs(S_TUT_Humans_Female_Magister_Priest_000" in that file (and look for such lines that end with "[add fact]" or "[delete fact]", you can see whether your initialisation code gets executed and if so, when (before or after the initialisation code of the tutorial goal).
