Spot on, Frank - thank you. (it works as desired, now). I'm not sure if anything is mentioned in the overview docs or help area, but perhaps that comment regarding assumed precision could be added somewhere obvious even to skip-readers like me?

Zoltan, The issue is discussed in the user docs for the MapInfo driver. The problem is TAB format specific so it doesn't belong anywhere more general IMHO.
BTW - any idea why the organizePolygons() routine bellows? Does it suggest an open polygon in my data-set, which then maybe engulfs the other polygons? Presumably 3-point polygons are classified as errors because the first and last points are counted as "2" ? Is there a way to get a coordinate or some debugging info to assist in finding the offending geometries?

It is not immediately obvious why there are problems. If the files are small you might inspect the geometries with ogrinfo to see if there are some odd ones. Adding "--debug on" to the commandline of ogr2ogr may give some useful details on the translation failure.
