What would that have to do with the file extension? If some Linux
systems decide that .ods and .pyz files are archives, it's probably
because they *are* archives in their own right (though specialized
ones).

Probably the libmagic (used e.g. by the `file` command) wasn't
up-to-date enough to specifically recognize OpenOffice documents, so
it simply recognized the ZIP file structure and detected the file as
such.
