I think the difference is the following :

The sort function without argument use the C locale for sorting.
In this case, the C collating sequence is the ASCII sequence, so
the "V" and "W" characters are differents.

When you use the argument, you use your locale ( LC_* and LANG 
environment variables )

At the prompt, the locale command gives you your environment for that.
In this case, depending on that, you can have "V" and "W" the same for 
sorting.

This is not python the problem, but the collating sequence depending on 
your locale. In your case, the "V" and "W" are similar for your locale.
