Incorrect sort order with value.sort and alphaGroup

[simbun]

I've recently started sorting my albums (except for compilations) by date so I can see when they were released in the context of an artists career, but I noticed that when drilling through certain values of an index I'd get the albums out of order, and after some testing I think I've found why.

Where an albums alphaGroup is in affect but the returned albums all fall under a single group (Album.value.sort={Date} all fall under #), if the number of albums returned is greater than the albums alphaGroup setting AND greater than the listViewAlbums setting, the albums are sorted incorrectly.

The easiest way to reproduce this is:
alphaGroup: albums=5
listViewAlbums: 5
tagValue: Album.value.sort={Date}

Then tag greater than 5 albums (that have different release dates) that start with the same letter, with a unique genre, then navigate to that genre and look under [n] albums.
