How is Alabama #5 for highest sales taxes?

How does Alabama rank #5 for highest state sales taxes in the country, when we also have a state income tax AND we're only one of a handful of states that taxes groceries? Tennessee is slightly higher at #2, but that should be expected as they don't have a state income tax.
