'Album Sort' - unexpected behaviour

[RSJ]

That is exactly what I do at the moment (I am responding to DavidL's comment). However, I also use the AlbumSort tag as a way of listing albums in the correct order. Otherwise, all dual-symphony albums which start, for example, 'Beethoven - Symphonies Nos. 6 & 7' appear before single symphony albums - e.g. 'Beethoven - Symphony No. 3'. I have got around this by have an AlbumSort tag of (for the example above) 'Beethoven - Symphony No. 6 & 7'.

However, Simon has indicated that different AlbumSort tags cannot be used for albums that have the same name - e.g. three versions of Beethoven's 9th symphony cannot have different AlbumSort tags if they all have the same Album tag.

What I had wanted to do was create a 'flight' of, say, Haitink's recordings of the Beethoven symphonies with the LSO, followed by the Karajan BP recordings. My plan was to do this by including the conductor's name after the first part of the album name in the AlbumSort tag (e.g. 'Beethoven Symphony Haitink No. 3'). This works if the Album tags/names are all different, but not if they are the same. So, where there are dual symphony recordings with different pairs of symphonies, there is not an issue. But a conflict is created for the single symphony recordings which have the same Album name.
