interpreting {(captcha)} markup consists roughly in executing
eval("return ($MarkupExpr['captcha']);");

so

>      $MarkupExpr['captcha'] = rand(100, 999);

results in executing:

eval("return (42);");

whereas:

>      $MarkupExpr['captcha'] = 'rand(100, 999)';


results as:

eval("return (rand(100, 999));");
