Sorry for the confusion.
The build-time options are purely used during build-time. They give you a place to hook into the CLI options and to modify mobile (iOS & Android) specific options that cannot be modified during runtime. I.e. environment or release.
Tags will get propagated to all layers when set during runtime so adding those to the runtime options should do the trick.

Alright, thanks! It would be nice if the documentation would be more clear on what properties can be set during build time, which can't be set and which ones must be set there.

Very true. We'll update those asap.
