Hi rpsimon‌, neither Classic Quizzes nor the New Quizzes does an import from Word.  It is a bit cumbersome.

Once the instructor has added all of the questions though, there is a Setting in new quizzes to randomize the question order and the answer order.  

I suspect since this is a newer quizzing tool an import option may be possible in the future as a lot of people have requested it from what I've seen in the past.
