Payment would not invoke modules if payment title is different than module name

Hunting through the payment.module, I found that the invoking of a module using "$txn->payment_method" under the review case does not work if the Title on the previous screen (selecting a payment method) was different than the module name
Example: Authorize.net uses "Pay with Credit Card" as its title. When you goto the review section, you'll notice that there is no payment method.

Altered the payment.module to call a new hook called 'modulename_name', which returns the name of the module for its title. Attached is an altered payment.module. Here is a code snipet from the authorize.net invokation of authorize_net_name:

function authorize_net_name($title) {
if ($title == t('Pay with credit card')) //example for a statically set title.
//optionally you could do: if ($title == variable_get('cod_title','')) for CODs (which should happen)
return "authorize_net";
else
return false;
}
