Well, I found the variable package-menu-async, which if toggled answers
my question.  If set to nil in the script, then packages to upgrade are
found successfully against the latest candidates.  If non-nil, as by
default, then things go wrong as shown, so answer is no.

And the working script boils down to:

╭───── [ upgrade_packages.el ]
│ (setq package-archives
│       (quote
│        (("gnu" . "http://elpa.gnu.org/packages/")
│ 	("melpa" . "http://melpa.org/packages/")
│ 	("marmalade" . "https://marmalade-repo.org/packages/")
│ 	("org" . "http://orgmode.org/elpa/")))
│       package-menu-async nil)
│ (list-packages)
│ (package-menu-mark-upgrades)
│ (package-menu-execute t)
╰─────
