do I need to make a subclass of MyWorld?
Yes. Any class needing access to the scores should extend MyWorld. No need (or rather, best is not) to modify the MyWorld class from how it is given here -- other than making it a title screen (showing name of game,, author and maybe instructions and credits).
what would be my SimpleActor?
The actors that display the score and the high score would both be. See lines 13 and 14.

What do I need to do from here in order for my high score to work.

Remove HighScore and Scoreboard classes entirely from your project. Create another subclass of World called MeteorWorld. Edit it so that it extends MyWorld and then move (cutting from MyWorld) prepare, SwitchScreen and addMeteor methods to MeteorWorld.

It should have been there when you first created the class.

If it is a subclass of MyWorld it wouldn't have a super call.
