The serialization format you're using (pathname followed by mode) is
not ideal for parsing.  I'd suggest putting the mode *first*, because it's
in a known, fixed format, and then the pathname second.  Obviously this
would require changing the script that's doing the parsing, as well as
the sort command (e.g. sort -z -k2), but it should be easier that way.
