ARRANGEMENTS letters in the order ABCD...

Interesting approach Tharwat, Watch out for duplicates(ish) , and sometimes gives strange results

 

It does when you have texts not in order .

Wow, splitting the list into two sets makes more sense. I stopped using entmod for string modification ever since ADESK introduced Annotative Text Styles

You'll note Lee's code is not using entmod on the entire DXF list. He's only sending the ename & text string items (codes -1 and 1) - so the issue with annotative text does not happen due to no change on the height code 40.

Bloody stupid of me sorry . Here's a fix for my code:

(defun c:SortTxt3  (/ sym ss eLst sLst)
 (vl-load-com)
 (initget "Ascending Descending")
 (setq sym (cond ((eq (getkword "\nChoose [Ascending/Descending] <Ascending>: ") "Descending")
                  (cons <= <=))
                 (t (cons <= >=))))
 (if (ssget "_:L" '((0 . "TEXT")))
   (progn (vlax-for eo  (setq ss (vla-get-ActiveSelectionSet (vla-get-ActiveDocument (vlax-get-acad-object))))
            (setq eLst (cons eo eLst)
                  sLst (cons (vla-get-TextString eo) sLst)))
          (vla-Delete ss)
          (mapcar 'vla-put-TextString
                  (vl-sort eLst '(lambda (eo1 eo2) ((cdr sym) (cadr (vlax-get eo1 'InsertionPoint)) (cadr (vlax-get eo2 'InsertionPoint)))))
                  (vl-sort sLst '(lambda (s1 s2) ((car sym) (strcase s1) (strcase s2)))))))
 (princ))

Reduced the ('s by taking a leaf from Lee's code

Thanks all, it was a fun challenge.
