I favored the flexibility of ordering concurrent notes differently in MIDI over having the sheet music uniquely define a program. It gives the programmer more choices in how notes can be combined. But there could be a default ordering -- I would think reading a chord from bottom to top -- for a piece of music where the score came first and the MIDI representation or performance of that score second.
