There are several things to do here:
- read the file
- split into records
- extract the byte count
- sort
- write the file in sorted order

Which parts are you having trouble with? What have you tried?

File reading and writing are covered in any Python tutorial. For the 
sort, I would make a list of
( byte count, record )
and sort that using the list.sort() method.
