Panel display order depends on registration order,
Sorry for the noise. On the bright side we no longer need to move
classes around to re-arrange panels.
ui/ --> startup/bl_ui
op/ --> startup/bl_operators
scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.
~/.blender/2.56/scripts/startup works for auto-loading scripts too.
