Use gdalbuildvrt utility for creating a virtual mosaic of your original files and use the resulting .vrt file as input for Mapserver.  It looks like normal tileindex system does not work correctly with WCS.  I have written some mails about this last week, have a look at the archives.

that area of scene h28v05, there is a observed data).
