    It took me a while to work out why there were so many unordered ways in
    areas I had been working.

    I now keep the "display segment order numbers" permanently checked so that I
    can see these misordered ways.  But even so I still find myself forgetting
    to check their order before uploading to the server. 

    I have to say both the maplint layer at infomationfreeway.org, and the JOSM
    maplint plugin are very useful for identifying them.

  The validator plugin helps quite a bit too, and the utils plugin helps a LOT with fixing some of the problems maplint finds... 

  Specifically re unordered segments, I've noticed some problems with longer ways not renumbering correctly in JOSM, splitting them seems to sort that out, there is a bug there somewhere...

  While I'm writing, I've got to say... JOSM, osmarender, Maplint, maplint's integration into T at H, T at H, the mappaint JOSM plugin, the validator JOSM plugin, the utils JOSM plugin, openlayers, and all the back end stuff that power the whole project are all great... yep, some bits have problems & some bits lack polish, some bits might not be needed if other bits were better etc... but... they're still all great and I'd like to give a big thanks to all the people who've spent large amounts of their own personal time to put these tools together... If I've missed any out, it's not because I think they aren't great, but, these are the tools that I have used most and find invaluable... 

  Thanks,

  d
+1 from me as regards the thanks 

As regards the longer ways, if these were not downloaded "all in one go by JOSM" because they went outside the original bounding box, then save the JOSM data, delete the layer and then reload the data and then reorder teh long way.  You might find that works.
