If I got you right, you want to have actors direction and position according to the previous scene?
It's quite easy, just insert this to your scene_init.script:
if (Game.PrevScene=="MyTestScene")
{
actor.SkipTo(x,y); // some coordinates there
actor.Direction = DI_DOWN; // seek other constants in documentation
}
In more than two exits I recommend using switch() for this condition though.
Hope that helps.
Edit: thanks Mnemonic. I had some weak moment writing it.
