Putting complete scores together is therefore a little bit more complicated than just making 80 playlists, unfortunately.
Quite right. As with many soundtrack CDs, some of the tracks on the discs combine several consecutive cues rather than keeping each one isolated. Not to mention that a lot of the tracked scores edited down the cues and only used portions of them. So recreating them would require a lot more work than just creating a playlist. You'd need software that would let you edit music tracks rather than just play them.
