it's here:

function ListSort(Item1, Item2: Pointer): Integer;
begin
// first take into account that parsed statements need to
be higher
// in the list than loaded ones
Result := 0;

if PStatement(Item1)^._Loaded and not
PStatement(Item2)^._Loaded then
Result := 1
else if not PStatement(Item1)^._Loaded and
PStatement(Item2)^._Loaded then
Result := -1;

// after that, consider string comparison
if Result = 0 then
Result :=
AnsiCompareText(PStatement(Item1)^._ScopelessCmd,
PStatement(Item2)^._ScopelessCmd);
end;
