change order of line items in Order Total Preview?

Hi - at checkout - the Order Total Preview has the subtotal, shipping, tax etc line items in a weird order. This is confusing for customers as it looks like tax is being added to the sub total plus shipping instead of just the sub total. It currently appears like this:

Subtotal: $35.00
Shipping: $10.00
Subtotal excluding taxes: $45.00
NY Sales Tax: $3.11
Order total: $48.11

Short of hacking core or doing some themeing work - how do I move the Sales Tax line item up so it is underneath the Sub total (and before Shipping)? In OSC you can set a sort order of all the different order total modules in Admin but I don't see anything here.

Subtotal: $35.00
NY Sales Tax: $3.11
Shipping: $10.00
Subtotal excluding taxes: $45.00
Order total: $48.11
