Thanks, even the following works
so the magic is to use
#+ORGTBL: SEND test orgtbl-to-latex :latex-default-table-mode math :environment pmatrix

_instead 

Of this
#+ORGTBL: SEND this orgtbl-to-latex-matrix :splice nil :skip 0


\[
A=
% BEGIN RECEIVE ORGTBL test
\begin{pmatrix}
 6 & 7 \\
 12 &  \\
 8 & 9 \\
 9 & 10 \\
\end{pmatrix}
% END RECEIVE ORGTBL test
B=
% BEGIN RECEIVE ORGTBL new
\begin{pmatrix}
 5 & 6 \\
 9 & 8 \\
  &  \\
\end{pmatrix}
% END RECEIVE ORGTBL new
\]
