Strange.  I don't specify anything anywhere in my initialisation files
about the @ symbol being special.  All I have in my files is:

#+begin_src emacs-lisp
(setq org-emphasis-alist (quote (("*" bold "<b>" "</b>") 
      				 ("/" italic "<i>" "</i>")
      				 ("_" underline "<span style=\"text-decoration:underline;\">" "</span>")
      				 ("=" org-code "<code>" "</code>" verbatim)
      				 ("~" org-verbatim "<code>" "</code>" verbatim)
      				 ("+" (:strike-through t) "<del>" "</del>")
      				 ("@" org-warning "<b>" "</b>")))
      org-export-latex-emphasis-alist (quote 
      				       (("*" "\\textbf{%s}" nil)
      					("/" "\\emph{%s}" nil) 
      					("_" "\\underline{%s}" nil)
      					("+" "\\texttt{%s}" nil)
      					("=" "\\verb=%s=" nil)
      					("~" "\\verb~%s~" t)
      					("@" "\\alert{%s}" nil)))
      )
#+end_src

I would have thought that =add-to-list= should have worked as well.  

However, I do have this customisation at the very *start* of all of my
org customisations, even *before* my =(require 'org-install)= line!  It
may be that these variables need to be set before you load org?
Alternatively, maybe you should use emacs's customisation methods to set
these variables?

HTH,
