I know there's easier ways to do this, but this should get you started.
This will get the highest number(s) in the file.

Code:
large=0
sort -rn FILE.TXT | while read line
do
top="$line"
if [ "$top" -gt "large" -o "$top" -eq "$large" ]
then
  echo "$top"
  large="$top"
fi
done

Franklin52's solutions work fine.

you can also go for

sort -n ref_file | tail -1 > new_file
