The code you have shown should not compile in ANY version of Delphi.
You are passing a pointer to a single Word where a TgtWordArray dynamic
array is expected. They are NOT the same thing!

You need to change your LLogClust variable from "array of Word" to
"TgtWordArray", and then pass that variable to AScriptRunCallback as
just "LLogClust" and not as "@LLogClust[0]":

var
  AScriptRunCallback: TgtScriptRunCallback;
  LLogClust: TgtWordArray;
begin
  ...
  AScriptRunCallback(..., LLogClust);
  ...
end;

That will then work in every Delphi version.

Make sure you are allocating memory for STable before you access its
elements:

SetLength(STable, ...); // desired element count

And also allocate memory for the PreAlloc field:

SetLength(STable[SomeIndex].PreAlloc, ...); // desired byte count

Unless PreAlloc is being assigned to point at an external preallocated
array instead:

STable[index].PreAlloc := SomeArray;

Yes, because you are assigning one array type to a different
incompatible array type. Every time you use "array of ...", you are
declaring a new array type. If you have two separate "array of Byte"
declarations, they are separate types, even though they use the same
underlying Byte type. This is covered in the Delphi documentation

http://docwiki.embarcadero.com/RADStudio/en/Structured_Types_(Delphi)#Dynamic_Arrays

If you want to assign the PreAlloc field to the Data field, You need to
change the PreAlloc field to TBytes so it matches the Data field:

type
  TGIS_FileTIFFSItem = record
    Data     : TBytes ;
    Dim      : Integer;
    PreAlloc : TBytes;
  end;
