If you expect decent computer skills, and you're just having humans read them, you shouldn't need to specify. If the candidate can't figure out to send you something you can be reasonably expected to read (sorry, MS Word.doc is included, but .docx isn't), that's good enough reason to disqualify them (from all directions - .docx, TeX, etc). If they're good enough that you'd ignore that, you probably don't need the resume anyway.
