You need to use sort command as follows:
sort -n -k 7 /path/to/input
OR
find . -type f -iname "pattern*" -ls |sort -n -k 7
OR
find . -type f -iname "pattern*" -ls |sort -r -n -k 7

Where,

1. -r – Reverse the result of sort.
2. -n – Numeric sort
3. -k 7 – Start a key at POS1 i.e. start sort key at # 7
4. -s – Stabilize sort by disabling last-resort comparison
