I cannot recall off the top of my head but I believe there is a separate DXF code for mtext entities with a length > 250.

(setq ss (ssget (list '(0 . "MTEXT")))) should select mtext entities regardless of length.

Try this:
Code: [Select]
(setq ss (ssget '((0 . "MTEXT")(1 . "*"))))

I don't understand fully what you are trying to do.

As far as I'm aware, I don't believe you can filter a selection based on the value of DXF group 3 for MTEXT, therefore, you will need to obtain a selection of all MTEXT entities which fulfill all other criteria, and then filter the selection further by iterating over the entities in the selection.
