After this

1) start Emacs with: emacs -Q -f find-file
2) press TAB two times so that the *Completions* buffer
   becomes visible
3) press C-x o

the window with the *scratch* buffer is selected.

It would be more convenient if C-x o in step 3 would switch to the
*Completions* buffer.

The basic idea behind C-x o is that it cycles through all live windows
before returning to the initially selected one.  We could, in your
special case, have ‘other-window’ select ‘other-window-for-scrolling’.
But if we do so, we have to face the dilemma that the next C-x o gets us
immediately back to the minibuffer window.  This means that all other
windows would get excluded from repeated invocations of C-x o.

So I'm afraid that I cannot offer a practicable solution for this :-(

No big deal.  I only noticed this because I had more than two windows
before doing a completion and in that case one has to type C-x o a lot
to to get to the *Completions* window.

A somewhat related question: Is there a command that cycles through the
windows in opposite direction as C-x o does?  I noticed that
<C-iso-lefttab> is not bound by default so I could use that.

There is no command that does (other-window -1).  You can obviously type
C-- C-x o to cycle backwards.

That's what M-v (switch-to-completions) does.

Another one I didn't know.  Thanks.
