What's the output of =M-x org-version= ?

Try this:

#+ATTR_LaTeX: :environment longtable :align |r|r|

Your example with the #+attr_latex line above gives this:

#+begin_src latex
\begin{longtable}{|r|r|}
\toprule
First & Age\\
Name & (years)\\
\midrule
\endhead
...
...
#+end_src

Keep in mind I'm using booktabs, so instead of \[top/mid]rule, you'd
get \hline with a default setup. Things look decent to me in the
output.

If you're on the "old exporter," see here for upgrading:

Good luck!
