I concocted a shell script, it looks promising:
#!/bin/sh
#-
# Parallel mounting of ZFS filesystems leaves a chaotic listing of
# mounted filesystems when viewed by df(1).
# Separating the header from the remaining lines and sorting the
# latter before recombining is a viable solution.
#-
DF=/bin/df
${DF} ${@} | grep ^Filesystem
${DF} ${@} | grep -v ^Filesystem | sort -k 6
# new-df.sh
