Quoting a list works fine in my org-agenda-custom-commands settings.
In fact, there are other variables that have quoted lists as their
setting, such as org-agenda-entry-types.

That's the problem.

It would make sense if org-agenda-todo-ignore-scheduled is 'all or
'past.

To use "or" logic to filter the agenda, I would recommend setting
org-agenda-skip-function.

--8<---------------cut here---------------start------------->8---
(setq org-agenda-custom-commands
      '(("W" "Work Schedule" 
         ((agenda "" 
                  ((org-agenda-skip-function '(org-agenda-skip-entry-if 
'notregexp ":\\(@Work\\|critical\\):")))
                   (org-agenda-ndays 1)))
          (tags-todo "@Work|critical")))))
--8<---------------cut here---------------end--------------->8---

Best,
