I don't think this will happen at least in the near term, as searching
out and creating/changing org export directives would be a major change
to the current behavior which inserts code results, and would cross some
semantic lines separating parts of Org-mode.

In this case I don't think the relatively limited convenience justifies
the added complexity.

I believe in this case the problem is caused by the lack of any headline
levels.  The LaTeX exporter can be weird about headline levels, try
adding a line like

* top

to the org file before the code block.  That fixes the problem on my
system.

Also, there is no way that an #+attr_latex line could affect the
execution of a code block, precisely because of the simplifying
separation of distinct components mentioned earlier.
