[Orgmode] agenda sorting time-up does not work anymore for me

[Rainer Stengele]

sorry if I missed the config but I cannot get the time-of-day specific 
todos to show at the top of my agenda (C-c a a) anymore (which means I 
had this working before?).

I have this sorting:

 '(org-agenda-sorting-strategy (quote ((agenda time-up category-keep 
priority-down) (todo category-keep priority-down) (tags category-keep 
priority-down))))

time-of-day items show up at the bottom of each day.

Please

Rainer
