Scenes vs. Cuelists

Forgive if this has been discussed, but I was wondering if scenes offer any advantages over cuelists, and if not, what is the idea behind them?
I am programming a new Full Boar using two touch screens, and I'm trying to use the screens for virtual subs. I have programmed a number of single-cue cuelists I plan to access from the touch screens, but it occurred to me maybe they should be scenes.
If there is a reason to change them, can I copy cuelists, including text, to scenes?
Also, I've noticed that touching a cuelist on the screen then hitting Enter will only sometimes execute the cue; about half the time I need to hit Enter two or even three times to get the cue to execute. Any suggestions for fixing this? Would scenes be any different?
I'd really like to be able to just touch the cuelist to execute it without then pressing Enter; I don't suppose there's any way to enable this?
