It's largely historical now. In the olden days, editing and recompiling 
a script would wipe the values of script local variables and set them to 
empty. That meant you had to add lines of code to re-initialize them so 
they'd still work after every edit. It not only made us crazy, it made 
the RR team crazy too, so one of the first things they did after RR 
obtained the engine was to change that. The option to go back to the old 
behavior is still there but I'd be surprised if anyone actually prefers 
to use it.

Generally "l" or "s", I prefer "s" myself. But it's entirely optional.

The engine doesn't care, it's just personal style.
