This can be fixed by removing the `literal' optional argument from
`replace-regexp-in-string' call in `org-macro-expand'.

I'm not totally opposed to it but it introduces a limitation: all
arguments must be strings. This is not strictly required, actually. As
a consequence, I slightly prefer fixing the current situation instead.

Is there any strong reason to force string?

You would also need to update `org-macro-initialize-templates' and
`org-export-as'.

Nitpick: this is equivalent to (arg-val)
