So it looks like in this particular case there is no way to favor one action over the other using routes. Perhaps a good way to do it for dynamiting actions would be to place several of them next to action 0 and forget the route system entirely. Then at spawn the engs will randomly select one of the dynamite actions and take the shortest route to get there. Since there will be more "clone" actions to choose from, the engs will wind up at the outside of the door more often, as desired. With a limit of 5 linked actions, it will be possible to create a weighting as much as 20%/80% if necessary. Looks like this might be the best way to do it.
