    If you have the ability to change the output of the shopping cart,  you could add a class to the 
 tag,  e.g. , , etc.
If you can't change your back-end,  then it's a choice of front-end tech.  The most cross-browser method is to use jQuery to apply the row classes.  The other alternative,  CSS3,  isn't supported by any current IE;  given that this is a shopping cart,  you're probably interested in the widest level of browser support.
Something like:
$('#shopping-cart-totals-table tr').each(function(n){
    $(this).addClass('row'+n);
});

Alternatively,  if you're only interested in the third item,  use jQuery in the same way as CSS3:
$('#shopping-cart-totals-table tr:nth-child(2) .price').addClass('highlightClass');
