Totals sorting aren't correct when using prices excl. tax

[ZieClaw]

Hello, I ran into this problem with Magento and PHP7 on websites using prices excluding taxes. Due to usort being changed in PHP7 it will not add the taxes to the grand total but instead substract it as if the prices are entered including taxes.

I also found a solution for this issue which is really easy, add a sort order to the MRSP tag like this in the config.xml file in the module.

<global>
    <sales>
        <quote>
            <totals>
                <nominal>
                    <class>sales/quote_address_total_nominal</class>
                    <before>subtotal</before>
                </nominal>
                <subtotal>
                    <class>sales/quote_address_total_subtotal</class>
                    <after>nominal</after>
                    <before>grand_total</before>
                </subtotal>
                <shipping>
                    <class>sales/quote_address_total_shipping</class>
                    <after>subtotal,freeshipping,tax_subtotal,msrp</after>
                    <before>grand_total</before>
                </shipping>
                <grand_total>
                    <class>sales/quote_address_total_grand</class>
                    <after>subtotal</after>
                </grand_total>
                <msrp>
                    <class>sales/quote_address_total_msrp</class>
                    <before>grand_total</before> <----------------------------- missing in magento
                </msrp>
            </totals>
        </quote>
    </sales>
</global>
