Radio tables creates a latex table including an enumerate environment,
which will not compile. This occurs if a numeric entry within the table
ends in a period. The problem does not occur without the period. It seems
possible that this is working as designed, but it is sure a surprise in
context.

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. |
-->
