My problem is: my agenda is very long and very cluttered.
I'd like to visually emphasize all lines
A) with priority A or deadline today
B) priority B and scheduled today or before today
 

I'm using org-mode 7.8.11 with Emacs 24.1.1 and I want to change the colors
used to display agenda lines, so that e. g. all lines with priority "A" are
shown in red bold font.

I tried to change the variable org-priority-faces but it has no effect:

 org-priority-faces is a variable defined in `org-faces.el'.
 Its value is (("A" :foreground "#E01B4C" :weight bold)
 ("B" :foreground "#1739BF")
 ("#C" :foreground "#575757"))

What am I doing wrong? Could other configurations overwrite this new
setting?

I tried a lot of things, but I must be doing something wrong with the
org-priority-faces values.

You should probably use customize to set the value. Setting it by hand
is possible (but not advisable) in this case, but you have to pay
attention to some details.  The docstring of the variable says

,----
| This is a list of cons cells, with priority character in the car
| and faces in the cdr.  The face can be a symbol, a color as
| as a string, or a property list of attributes, like
|     (:foreground "blue" :weight bold :underline t).
`----

so you need to set it with something like this:

--8<---------------cut here---------------start------------->8---
(setq org-priority-faces '((?A . (:foreground "red" :weight "bold"))
			   (?B . (:foreground "yellow"))
			   (?C . (:foreground "green"))))
--8<---------------cut here---------------end--------------->8---

?A is elisp syntax for the character A. That's different from the string containing
A which is denoted "A". As the docstring for the variable indicates, it expects
a *character* as the car of the pair.

OK - sorry I screwed that up.

Probably the "Emacs Lisp Intro" tutorial which comes with your emacs I believe:

C-h i m Emacs Lisp Intro RET

No wildcards used here - not sure what you mean. If you mean the ? in ?A it's
most definitely *not* a wildcard.

These are obscure (but hallowed by long history) names of the basic operations
in Lisp. Lisp's basic data structure is called a (dotted) pair: cons takes two
things and constructs a dotted pair out of them. car and cdr (the names mean
nothing unless you happen to know the architecture of some ancient IBM computer
where Lisp was first developed) are selectors: car takes a pair and returns
the first part of it, cdr returns the second part.
