A slightly different approach would be to defer the "human" size to later,
and enable to do any calculation you want manually, then convert to human sizes with "numfmt":

    du -s * \
       | sort -n \
       | awk '{ sum+=$1 ; print } END { print sum, "Total" }' \
       | numfmt --to=iec

One more thing: instead of 'du -s *', perhaps 'du -d1' would work better (depending on your needs), as it will print sizes used only by directories.
