This works in mksh 35b:

n=0
du | sort -n |& 
while read -p size dir
 
do
  if [ "$size" -gt 1000 ]
  then
    n=$((n+1))
  fi
done
echo "Found $n too big files"

This works in pdksh_5.2.14-30ubuntu1_amd64.deb :

#!/bin/ksh
n=0
(du | sort -n) |& 
while read -p size dir
 
do
  if [ "$size" -gt 1000 ]
  then
    n=$((n+1))
  fi
done
echo "Found $n too big files"

exit 0
