From what I can tell by how lang files are used, in addition to linking to them in the resources.cfg file, you also have to link to it in your main config file. The other thing is that it seems like the config file only really has a slot for one lang file for your in-game text - the one listed by DefaultGameLanguage. By default, this is the english.lang file that is either in the config folder or a subfolder of the config folder. Since that file generally has stuff already in it, I'd recommend that you copy the one from SOMA's config folder and add your stuff to the bottom of it.

Another thing that I've noticed is that since the SomaDev.bat launcher doesn't load your mod's config files (it just loads the map information), it isn't going to get your lang file either. Because of that, when you run your mod through the DevBat, all your lang stuff isn't going to display. If you run it through the ModLauncher though, it should display just fine.
