How to make copied text appear in the correct order?

I have a PDF document with text created from a Photoshop file.

There were multiple text layers in this Photoshop document.

Problem:

When I do "select all text" in Acrobat and then "copy" and then paste it into a text editor the text is pasted out of order.

This is somewhat expectable because of the multiple text layers in the original Photoshop file.

Question:

How can I tell Photoshop the desired order of the text layers when creating the PDF file?

The layers are stacked in the correct order in the layer panel in Photoshop. I was hoping that was the issue, but it's not. Is there any other way in which I can specify the text order?

Your help will be much appreciated!
