I had mine bought when it first came out, stored away and got it for Christmas that year. My Tetris had the standard music-A, but I have seen a cart before with the other and it was a US game so I guess it would have been 1.0.

As far as Super Mario Land goes, that was the one game I got with it (and ruined their surprise accidentally opening it first.) Do you have an example of this percussion bit? As far as I recall when you'd die it just did few notes, same with that fanfare thing when you hit the gate up top.
