Cant sort a column with custom type

Hi,

im trying to add datatables to the table on http://www.kickwelt.de/infos.phtml?cat=1&d1=7&d3=2

The last three columns have a specific numeric format (dots as thousand seperators and commas as decimal seperatos). To sort them i used the "Commas for decimal place"-sorting plugin and modified it to replace all dots with "":

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
    "numeric-comma-pre": function ( a ) {
        var x = (a == "-") ? 0 : (a.replace( /./g, "" )).replace( /,/, "." );
        return parseFloat( x );
    },
 
    "numeric-comma-asc": function ( a, b ) {
        return ((a < b) ? -1 : ((a > b) ? 1 : 0));
    },
 
    "numeric-comma-desc": function ( a, b ) {
        return ((a < b) ? 1 : ((a > b) ? -1 : 0));
    }
} );]

But when im trying to sort this columns, it does nothing.

Here is the link to the debugger:

If im getting it right the type "numeric-comma" doesnt exist, does it?

How can i fix this?
