The execute bits were set:

-rwxr-xr-x   1 jeff     jeff          372 Nov  2 02:16 jython

I think what happens is this: 

On Unix, EOL corresponds to <LF>. On Windows it corresponds to <CR><LF>.
So when the script is saved in DOS file format, the first line reads:

#!/bin/sh<CR><LF>

The shell reads everything up to EOF *on Unix*, ie <LF>, resulting in:

#!/bin/sh<CR>

It then tries to find the file, and can't because of the <CR>, so it
fails with the error message:
bash: ./jython: No such file or directory

ie, it's saying "there's no file called "/bin/sh<CR>".

Rather nasty :)
