No, Scribus can not import styles from MS Word.
If you however import text from an Open Office document Scribus will create styles for that text.
So, you can open the MS Word document in OO, make sure there is text using all the styles (I am not sure if that is necessary, but I don't think Scribus will import unused styles) and save as ODT. The create a Scribus document, import the ODT file, and save the Scribus document. The you can import styles from that document into the document you are working on.
I would do som testing first to see what styles get imported and how they are named (I have never tried importing ODT files).
