You should preserve the order of elements from the spec for readability. So
payerEmail and payerPhone should go below shippingAddress.

[
    RuntimeEnabled=PaymentRequest,
] interface PaymentResponse {
    readonly attribute DOMString methodName;
    [CallWith=ScriptState, RaisesException] readonly attribute object details;
    readonly attribute PaymentAddress? shippingAddress;
    readonly attribute DOMString? payerEmail;
    readonly attribute DOMString? payerPhone;

    [CallWith=ScriptState] Promise<void> complete(boolean success);
}

     [CallWith=ScriptState, RaisesException] readonly attribute object details;
     readonly attribute PaymentAddress? shippingAddress;
