I think the doc should specify "all else being equal" - my own trail and
error testing seem to suggest that when versions are equal, Guix will then 
prefer the
package specified by "-L" or "GUIX_PACKAGE_PATH" - however a higher version 
seems to always win, wherever it is specified.

2 Caveats -

This is just by observation only, perhaps someone else can
comment if this is intended or not.

I used time-machine to test this but I don't think that
should change things.  I was able to move backwards and forwards in time
vs a local package I have specified.  My local package was taken when I
moved backwards in time, but when I moved forwards to a newer version in
Guix it took the remote package instead.  When the package was the same
as remote it took the version with a local location - as far as I can
tell.
