Hmmm - tried this and it still doesn't work.  My contour style has 
exactly the same levels as the base style, and the mapnames are higher. 
  All I can see is the contour labels, but not the contours themselves 
(see http://cferrero.net/maps/img/mkgmapdev_contourissue.png).  If I 
just display the contour maps and not the basemap, it works as expected 
(see http://cferrero.net/maps/img/mkgmapdev_contourissue2.png)

I'm using Mapsource 6.16.3, my base map has mapname 63247001 and the 
contour tiles are 63247201-63247209, compiled with higher draw priority 
and --transparent

The levels definition in both basemap and contours is
levels = 0:24, 1:23, 2:22, 3:20, 4:18, 5:16
