Well I wasn't aware of it before, but I just looked at
guile-readline/readline.c and noticed that there is a write-history
primitive:

SCM_DEFINE (scm_write_history, "write-history", 1, 0, 0, 
            (SCM file),
"")
#define FUNC_NAME s_scm_write_history
{
  char *filename;
  SCM ret;

  filename = scm_to_locale_string (file);
  ret = scm_from_bool (!write_history (filename));
  free (filename);
  return ret;
}
#undef FUNC_NAME

Is that a solution for you?
