Sort method in noise is not working properly

[Gero.Bare]

This is different of sorting criteria, the sorting method doesn't work properly.

Example: Ordering by album or track length gives a semi sorted query but not a properly sorted one
I.e:

^ Track length
13:40
12:28
12:52
12:20

Or similarly sort albums gives almost properly sorted album except the first/last result sometimes is exchanged with a song of the previous/next album. This probably happen for every criteria.

This is valid as the current revision (as today was 1690). And is valid for Column view and list view.
