I believe that r.out.tiff will export using colors, not data.
Add the -t flag to get a world file & so make it a geotiff.

In GRASS 6.4 the d.out.file module is another option, set the
size= parameter to the number of rows and columns, and select
format=geotiff.

The default color table is "rainbow", see the r.colors help page
for details.
