Thank you for the reminder.  I've just installed a fix.

When Emacs creates the initial frame and selects the default
font, "(add-to-list ...)" is not yet evaluated, so if your
default fonts is 'Courier New', it is opened without
scaling.

What I currently don't understand is that the font rescaling
doesn't work for the default font in the above case even
after (clear-face-cache t).  I'm now investigating the
reason.

Font rescaling is a bit weird, though.

Using a test file with just two lines:

aeiou
áéíóú

and running emacs with this:

  emacs -q --eval "(add-to-list 'face-font-rescale-alist '(\"Courier
New\" . 1.5))" test.txt

the fonts used for the two lines are, respectively:

    uniscribe:-outline-Courier
New-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1
    uniscribe:-outline-Courier
New-normal-normal-normal-mono-19-*-*-*-c-*-iso10646-1

so the fist line appears normal, while the second one is rescaled.
