nl_tokens: return text string value by adding up ascii value so the text is somewhat sorted when using a digital sort this is NOT an alphanumeric sort
pl_tokens: function ( val , num , <mask> ) { if ( max ) { // make sure the text value is greater than the max numerical value (max) var indx , len = val ? val . length : 0 , n = max + num ; for ( indx = 0 ; indx < len ; indx ++ ) { n += val . charCodeAt ( indx ) ; } return num * n ; } return 0 ; }
