Thanks to DTB's suggestions, I modified the script and now it's much
more compact and simple. Here's a copy of it:

usage() {
  echo "usage: vol up"
  echo "       vol down"
  echo "       vol get"
}

get_vol() {
  pattern="$MIXER_VARIABLE=[0-9][0-9]?[0-9]?,"

  current_vol=$(mixerctl "$MIXER_VARIABLE" | sed -E s"/$pattern//")
  perc_val=$(echo "(100 * $current_vol) / 248" | bc)
  echo "$perc_val%"
}

case "$1" in
   up)   mixerctl -w "$MIXER_VARIABLE+=$INCREMENT" ;;
   down) mixerctl -w "$MIXER_VARIABLE-=$INCREMENT" ;;
   get)  get_vol ;;
   *)    usage; exit 64;; # sysexits(3) EX_USAGE
esac
