Comment 2 for bug 614392

sorry for the sorting issue - it works as you described
but the sequence should be displayed in taxes in account.tax.tree to avoid this sort of errors

<?xml version="1.0"?>
<tree string="Account Tax">
                    <field name="sequence"/>
                    <field name="name"/>
                    <field name="price_include"/>
                    <field name="description"/>
                </tree>

for layout and missing tax please see attachment
