I don't know anything about asymptote and I am not sure whether this
will help: it does produce a temp file with everything quoted and
running asy on the temp file produces an .eps file that contains the
diagonal line, but it produces a png file which seems somewhat peculiar
to me but maybe it'll work for you.

You have to do

(setq org-babel-min-lines-for-block-output 0)

in order to get the example block result.

I just added a python block to produce another table with everything
quoted.  The second table is then give to asymptote:

--8<---------------cut here---------------start------------->8---
#+data: values
| 0 | 0 | a |
| 1 | 1 | b |
| 2 | 3 | c |

#+begin_src python :results output :var table=values
  print "#+data: qvalues"
  for row in table:
      print "|%s|" % ("|".join(map(lambda x: "\"%s\"" % (x), row)))
  
#+end_src

#+results:
#+begin_example
#+data: qvalues
|"0"|"0"|"a"|
|"1"|"1"|"b"|
|"2"|"3"|"c"|
#+end_example

#+begin_src asymptote :file asy.png :var v=qvalues
   size(100);
   draw((0,0)--(1,1));

#+end_src

#+results:
[[file:asy.png]]
--8<---------------cut here---------------end--------------->8---


The temp file looks like this:


--8<---------------cut here---------------start------------->8---
string[][] v={
{"0","0","a"},
{"1","1","b"},
{"2","3","c"}
};
size(100);
draw((0,0)--(1,1));
--8<---------------cut here---------------end--------------->8---

I attach the asy.png file I get.
