Using org 8.2.4 (8/18/2014), here is a complete example:
<!-- BEGIN RECEIVE ORGTBL test -->
<!-- END RECEIVE ORGTBL test -->
<!--
#+ORGTBL: SEND test orgtbl-to-latex
| 0. |
-->
C-c C-c on the SEND line produces this:
<!-- BEGIN RECEIVE ORGTBL test -->
\begin{tabular}{r}
\begin{enumerate}
\item
\end{enumerate} \\
\end{tabular}
<!-- END RECEIVE ORGTBL test -->
<!--
#+ORGTBL: SEND test orgtbl-to-latex
| 0. |
-->
