Tablesorter sortForce bug

Tablesorter sortForce bug

The documentation says:
sortForce: Use to add an additional forced sort that will be appended to the dynamic selections by the user.
but it doesn't work as advertised.
If you look at the example page:  TableSorter sortForce Example
The sortForce is set to the first column (First Name) ascending. If you click on Total to sort you will see that it doesn't sort by the Total but instead it is still sorted by First Name. This isn't what sortForce says it does.

Oh and by the way the example page says:
// set forced sort on the fourth column and i decending order.  
which is not the fourth column, missing the letter "n" for "in", and descending is spelled wrong.
