        One solution would be to rename the rasters from raster.1
        .. raster.1000 ... to raster.00001 .. raster.01000 ...,
        e. g. (in Sh):

GRASS> g.mlist type=rast pattern=raster.\* \
           | sed -e 's/\([0-9]\+\)$/ \1/' \
           | (while read pfx num ; do \
                  padded="$(printf %5d "$num")" \
                  g.rename rast="${pfx}${num}","${pfx}${padded}" \
              done)

        (The script is probably worth wrapping in a Sh script file.)
