Hi Grobe,
I think there is a way to alter the order in which the attachments appear. Although I haven't tested this specifically, I have used it otherwise.
After you upload the file, there are 2 buttons. I can't remember what one of them is (it might be "Delete the file" now that I think about it) but the other is something like "Place Inline". So wherever the cursor is placed in the text field is where the attachment is placed within the message, when you click that button. I have found that after I use that button, I can use cut/paste or copy/paste to move it around within the message. I don't know that I've specifically tried to reverse the order of the appearance of the attachments, but I suspect that it can be done.
Possibly you might have to put some kind of text in between the files, even just a dot/period (.) to make it work, but I'm really speculating at this point.
If you want to make some kind of "test message" in the Help forum (where attachments are allowed) I will be glad to delete it after you've learned whether it can be done
