Reading what I've written, the multiple use of the terms scene and scene director make it as clear as mud. Sorry about that. Here's another go.
1. Create your scene for your score bar (call this Score Bar).
2. Add the various scene directors to it that you need to animate the different parts of it that you're wanting to do (Flag, Touchdown, PlayClock)
3. Create another scene called Flag Trigger
4. In that scene's default scene director, add a scene trigger event that triggers "Flag" in "Score Bar" (you can actually do that).
5. Do steps 3 and 4 for the other animations.
6. Using RossTalk, take the scenes created in steps 3 and 4. These will then in turn trigger the scene directors in Score Bar.
I hope that's more clear.
