That's an interesting situation (many titles for a same tracklist).
But, in my opinion, in this particular case, there is no problem.
The number is just a price indication.
We have here re-releases at cheaper price of the very same compilation (as you said).
2000-05-01 B00005FH8U full price first release (or so it seems)
2005-06-25 B0009N2V0A nice price edition 1,200円
2007-06-06 B000NO2AGK cool price edition 1,000円
The title of the existing MB release, I think, is best chosen. It takes the title which is written on the cover.
You can add the 3 ASIN (Amazon ID) as URL relation for the release if you want to do something.
You can also add a japanese version release with the titles written on the Amazon tracklists if you want, though it may not really be necessary.
But changing the title is not needed here.
Sorry I forgot the question : You should add the 3 release events yes that's the correct thing to do! (^_^)
