[O] Custom agenda 'tags-todo' sorting by scheduled data note working

[Gabriel Duven]

Hi guys,

I created a custom agenda view with tags-todo, which I like to sort by 
scheduled date.

(add-to-list 'org-agenda-custom-commands
      '("u" "Next actions" tags-todo "+PRIORITY=\"A\""
         ((org-agenda-overriding-header "Critical")
          (org-agenda-prefix-format " %-5:c")
          (org-agenda-sorting-strategy '(scheduled-down))
          (org-agenda-todo-ignore-scheduled 'future)
          (org-agenda-tags-todo-honor-ignore-options t)))
        )

But sorting comes out wrong: It's not sorted by the scheduled date. In 
fact, it's not sorted at all, but seems to keep order of 
org-agenda-files.

Anybody help? Thanks a lot in advace!! Orgmode is great :)
