Hi Graham,

We can see what's going on here by executing the block manually with C-c
C-c, which transforms your results block from this:

#+ATTR_LaTeX: width=10cm
#+results: BoxplotFlowering
[[file:FloweringBoxplot.pdf]]

into this:

#+results: BoxplotFlowering
[[file:FloweringBoxplot.pdf]]
#+ATTR_LaTeX: width=10cm

(The reason is that the results block corresponding to the code block is
first deleted and then re-inserted immediately below the code block).

You are using ':exports both' which means that the above transformation
actually occurs during export, but in a special pre-export org buffer
which the user never sees. The fact that the ATTR_LaTeX line ends up
last explains why it modifies the *second* block.

Thanks for pointing this out -- we will revisit this behaviour as it
does seem surprising and on the face of it undesirable.

As a workaround, is it necessary for you to execute the block on export?
Or could you instead use :exports code? I.e. before export, execute the
block manually and ensure that the #+ATTR_LaTeX and #+results lines are
arranged in the correct way.
