Yes, sorting is in fact the simplest form of shuffling to perform, so that's an option to consider. Any adjacent sortings would be directly visible, so that's easily (?) tested.
EDIT: The easiest start with this would be to look at first vords of lines. The fact that paragraphs start with gallows may be just the effect of vertical sorting. Looking at f2r, we observe k-d-q in the first paragraph, then again k-d-q in the second paragraph, then in f2v, second paragraph, it's k-d-d. Does this sustain further?.. Have no time to check right now.
