If the registry value were just a script path, you'd have to modify
your script to chain to the previous script, if any. Since it's a
command line you can simply use the & operator to append another
command.

Do you really intend for your batch file to be run every time cmd.exe
is executed, including every time that every program on the machine
calls the CRT system() function?
Why don't you just install a shortcut to a batch file that starts a
command prompt with the extended PATH?

system('reg...') won't be able to do that unless you export the key to
a .reg file and parse the existing AutoRun value. It would be simpler
to use subprocess.check_output('reg query ...'), but simpler still and
more reliable to just call QueryValueEx.
