This can be achieved, as has been shown by you and by Bastien, using
special user-defined commands.

Another option, maybe simpler, is to use the local options in agenda
custom commands to insert a function into `org-agenda-skip-function'.

For example, I can write this function:

(defun org-agenda-skip-if-scheduled ()
   "Function that can be used in `org-agenda-skip-function',
to skip entries that have been scheduled."
   (let (beg end)
     (org-back-to-heading t)
     (setq beg (point))         ; beginning of headline
     (outline-next-heading)
     (setq end (point))         ; end of entry below heading
     (goto-char beg)
     (if (re-search-forward org-scheduled-time-regexp end t)
         end   ; skip, and continue search after END
       nil     ; Don't skip, use this entry.
)))

and then define a custom command like this:

(setq org-agenda-custom-commands
     '(("b" tags "@SHOP"
         ((org-agenda-skip-function org-agenda-skip-if-scheduled)))))

org-agenda-skip-function should *never* be set with `setq' or so,
but you can use the options field in custom commands to temporarily
assign a value.

The next version will have two functions,
org-agenda-skip-if-scheduled and
org-agenda-skip-if-scheduled-or-deadline
built-in, so it will be easier to find entries that have no deadline 
and/or
have not been scheduled.  For your specific application, I guess you
also have to look at the timestamp and see if it is in the future.
Having seen your other lisp code, I guess you can do this yourself.

Hope this helps.
