If you change your naming convention a bit it would be easier.
Save the files as sql_20031014.gz - in YYYYMMDD or YYMMDD format instead.
#!/bin/bash
cd /root/junk
backup=($(ls -1 sql_*.gz|LC_COLLATE=C sort -r))
# Show whats in the array
for ((i=0; i<${#backup[*]}; ++i)); do
echo "${backup[i]}"
done
# If you know you don't want to touch the first 4 entries
# start a loop at 4 and delete all the remaining files.
for ((i=4; i<${#backup[*]}; ++i)); do
echo "Would have erased - ${backup[i]}"
done
