Just to make sure I am not missing something in that case:
package-load-all-descriptors reads package descriptors either in
alphabetical order or in the order the operating system will list them
in the elpa/ directory.  Via package-load-descriptor, the descriptor
expression is passed to the package-process-define-package, which will
insert them into package-alist according to the version number.

If this is so, then if the package developer does not bump the commit to
something else after releasing the package on GNU ELPA, then order of
the VC package vs. the tarball package would depend on order in which
they are returned from via `directory-files', since their version
according to `version-list-=' would be the same?
