turn order in Social Physics AKA Skyrim's Social NPCs mod

[DrAltaica]

Well Prom Week's source has been put on github.
The game on working has the player scheduled his characters day like Slave Maker 3 (Also had it's source released. Sorry can url tag doesn't work with Magnet links see it at the end of post)
I'm wondering how I should end the scenes. Should I assign a length of time to each action then when the time runs out the scene ends Should I just give the player a limited number of actions. Each character a limited number or actions and how should I decide when the NPCs take actions?
