The only caveat, the file has to have Unix ending, not Mac ending.

Deivy,

You may consider the shell command tr

tr '\r' '\n' < unsortedfile |sort -n -t '.' -k 1,1 -k 2,2 -k 3,3 -k 4,4 |tr '\n' '\r' > sortedfile


Excellent.
Thanks Bill. However, the last part should only be used *if* you want a Mac file not Unix. Which might not be the case.
Some apps use Unix file endings not Mac. Script Editor is one.
