MIXXX does not maintain track order importing M3U playlist

[ShockPop]

as mentioned in the Boards, I've found that MIXXX does not maintain proper track order when importing M3U playlist that was created in WinAmp

Here's is the text version of the attached m3u playlist for comparison (if it's helpful)

1. Welcome To The Show (0:50)
2. The Pillbugs - The World's Most Harmless Villain (4:08)
3. Mark Mikel - 2010 Anthem (3:08)
4. Marikesh - Mother's Eyes No. 1 (3:31)
5. Chris Shutters - By Now (5:09)
6. The Pillbugs - Ball Of String (2:09)
7. The Pillbugs - The Kick-Around Boy (3:02)
8. The Pillbugs - I'd Give It All Up For You (2:18)
9. The Pillbugs - Heather (Whatever) (2:41)
10. The Pillbugs - Pretend You're Not Home (1:53)
11. Mark Mikel - ShockPop plays all Bugs (0:25)
12. The Pillbugs - Emily Loves (1:55)
13. The Pillbugs - Meddle With Me (3:36)

Hi Guys, excellent work on the 1.11 release. I am migrating from 2 other DJ packages to MIXXX but also find that in 1.11, mix does not maintain track order in either M3U import or playlist import from Traktor 2.6.2 . For direct m3u import, the workaround seems to be to select all in the Library and reset play count (imported list tracks already exist in the library and have a play count) as the behaviour seems to be to bring most frequently played tracks to the top of the play order. This really messes up things for me over a ~140 track playlist. Be good if this was configurable in Preferences.
Also the use case for traktor library is to right click a playlist in the traktor library view on the left, then 'Import Playlist'. Track order gets scrambled, once you select another playlist then switch back. Seems to sort roughly on Artist instead, reseting playlist order. Again a bit of a disaster over 120 tracks. Workaround is to select the traktor playlist on the left, then select all tracks in the right pane, rt click 'Add to Playlist', having created it manually first . I need to migrate about 210 playlists, not great.
Platform is Windows 7, MIxxx 1.11.0, Traktor 2.6.2 , m3u files from Musicmatch Jukebox.
BTW the primary reason for moving to MIxxx is that the playlist export is excellent, it does not drop latin accent characters in track filenames, Traktor playlist export is rubbish for this. Use case is copying the live playlist to ITunes/Ipod/ipad for backup plan.
Cheers for the good work so far.

We should probably have a separate bug for Traktor 2.6.2 playlists not being in order.

Looks like this was caused when a mix of the tracks in the M3U are already in your library.

Repro steps:

1) Add a whole album to a playlist in order.
2) Export an M3U
3) Clear the playlist, remove some of the tracks from the album from your library entirely (via hide then purge)
4) Import the M3U into the playlist.

Tracks are out of order (specifically, the ones that were already in the library come first (in the order they were in the M3U) followed by the tracks that were not in your library already (in the order they were in the M3U).

I added a re-sort phase in TrackDAO::addTracks that keeps them in the order specified by the M3U.
