So ogr2ogr is doing the reprojection correctly, but writing the wrong coordinate system string to the resulting MapInfo file. Is that correct? I'm not a developer and I have not looked at the source code, so I am guessing, but there might be a look up table defining the MapInfo coordinate system string for a matching proj4text string. You might look in the source code for that, or you might want to file a ticket.
