I'm starting on a textbook project using a similar set of tools.
I'm making progress, but am still finding lots of little snags; perhaps as we
both proceed we can share what we've learned.
In any case, using temporary file names is a good idea, which hadn't occurred to
me. But I guess it's easy to do, using something like
#+CAPTION: A test caption.
#+begin_src asymptote :file (org-babel-temp-file "figure-" ".pdf")
size (1cm, 0);
filldraw (unitsquare, red);
#+end_src

How would one implement this behavior in LaTeX?

This was one of the "snags" for me that I mentioned above. But this
works:
#+CAPTION: A test caption.
#+Attr_LaTeX: width=\textwidth
#+begin_src asymptote :file (org-babel-temp-file "figure-" ".pdf")
size (1cm, 0);
filldraw (unitsquare, red);
#+end_src

Haven't done this, but the LaTeX code could put the answers and
solutions in a float, which could then be floated to the end of the
document.
