I can confirm the Problem on Windows 7 Enterprise 64bit
Opening the .mscz with 7zip and then dragging the .mscx into MuseScore works. The Problem seems to be that the META-INF\container.xml uses Unicode, but Windows file system does not, it is using ISO-8859-1 instead?

works for me from command line and from file dialog (linux ubuntu)
