I have discovered how to do this - leaving question up in case it helps anyone else. The correct syntax for this is:

tooltip: {
  formatter: function() {
    return ''+
           this.x +': '+ this.y +
           (this.series.name == 'Recovered(%)'||this.series.name =='Defaulted(%)' ? '%' : '');
  }
}
