Hi Neil,

Are you using the latest version of Org-mode?  I ask because all of your
examples work as expected on my system, specifically I get the
following...

Best,

#+NAME: test(foo="bar")
#+BEGIN_SRC sh :session :results output verbatim replace
  echo "1. foo is $foo"
  echo "2. foo is ${foo}"
#+END_SRC

#+RESULTS: test
: 1. foo is bar
: 2. foo is bar

. . . but this is fine:

#+NAME: test2
#+BEGIN_SRC sh :var foo="bar" :session :results output verbatim
replace
  echo "1. foo is $foo"
  echo "2. foo is ${foo}"
#+END_SRC

#+RESULTS: test2
: 1. foo is bar
: 2. foo is bar

#+RESULTS:
: 1. foo is bar
: 2. foo is bar

When I tried this:

#+CALL: test("baz")

#+RESULTS: test("baz")
: 1. foo is baz
: 2. foo is baz
