I just finished entering "Moonlight Sonata" into Musescore. I didn't have any problems entering all the music (triplets, multiple voices, etc.) and it sounds fine except for the sustain pedal. When I play it on the piano, I use the pedal according to the sheet music. But I can't find any way to add the sustain pedal lines to my score. And even if I could add them, would Musescore simulate a pedal sustain? It just doesn't sound "right" without the pedal. Maybe this will be in the 2.0 release. My only option is to possible add another instrument track and fake it with something.
