Yep, this was a mistake in the template.  Fixed now.

OK, this works now as well.

And you can pass options to the columns environment and to the column
environment by preceeding [..] with "c" or "C", like this:


* This is a frame
** Block starting also a column   :BMCOL:B_block:
   :PROPERTIES:
   :BEAMER_env: block
   :BEAMER_envargs: [op-for-block] c[opt-for-column-env] C[opt-for- 
columns-env]
   :END:

Not strongly tested, but I hope it works...
