А RecordSortedList.sortOrder(...) метод использовали?

Вот это работает, например:

static void testRecordSortedList(Args _args)
{
    TmpABC tmpABC;
 
    RecordSortedList rslTmpABC = new RecordSortedList(tableNum(tmpABC));
 
    rslTmpABC.sortOrder(fieldNum(tmpABC, ItemId));
 
    tmpABC.ItemId = '1';
    tmpABC.Amount = 1.0;
    rslTmpABC.ins(tmpABC);
 
    tmpABC.ItemId = '2';
    tmpABC.Amount = 2.0;
    rslTmpABC.ins(tmpABC);    
 
    tmpABC.ItemId = '3';
    tmpABC.Amount = 3.0;
    rslTmpABC.ins(tmpABC);    
 
    tmpABC.ItemId = '2';    
    rslTmpABC.find(tmpABC);
 
    print tmpABC.Amount;
    pause;
}
