Which browser returned these mimes and which other browsers did you test to return the mime of those files?

Welcome to CI Anderson, thanks for sharing. In addition to xwero's questions, what are those, a version of Office? Which version?

These files are part of the Office Open XML specification, an invention by Microsoft which is used on Office 2007 (Windows) and Office 2008 (Mac).

I did a quick test with a .docx file, Safari (3.2.1, Mac) did report the same mime type.
