Texinfo-mode does not call prettify-symbols-mode (I believe no mode does 
that by default), which is why I wrote:

If you want to turn [prettify-symbols-mode] on by default, do:

(add-hook 'texinfo-mode-hook
          (lambda ()
            (push '("\\alpha" . ?α) prettify-symbols-alist)
            (push '("\\beta" . ?β) prettify-symbols-alist)
            (prettify-symbols-mode)))

In the last line, "(prettify-symbols-mode)" calls prettify-symbols-mode. 
If you want to see the code of "prettify-symbols-mode", type C-h f 
prettify-symbols-mode RET TAB RET.
