I can also confirm that org-try-cdlatex-tab outputs "t" in all cases but does not expand in align environment.
I noticed that cdlatex-env-alist-default does not include the align environment. I tried to add it to "Cdlatex Env Alist" in the customize browser but it did not change the behavior to what I expect. I skimmed through cdlatex.el but did not find anything suspicious. I am not a hardcore lisp coder though.
