I've heard that the chapter in Tur (and, consequently, Shulchan Aruch) that deals with the shofar is number 586, the gimatriya of "shofar". I've also heard that the chapter number (240) for tz'nius (in Orach Chayim) matches that for kibud av vaem (in Yore Dea) as a way of teaching us that parents' tz'nius can lead to the children's kibud for them.
I'm seeking a list of such intentional chapter numberings in the Tur: those that were intended by the author to be meaningful. Can you please supply whichever you may know about?
Part of the reason I suspect they may really exist (besides, of course, that I've heard they do, as mentioned above) is that the Tur's author refers often to gimatriya and acrostics in his short commentary on Chumash.
Note: I'm not seeking whatever interesting chapter-number facts you might happen to notice, or someone else noticed. Rather, I'm seeking only such chapter-number facts as some Judaism authority has claimed were intentional on the part of the author of the Tur. Every answer below should cite some source that not only indicates the interesting number fact but also claims that that was the author's intent. (Thus, too, I hope that some answer(s) below will contain the shofar and tz'nius facts, since I currently have no source for them.)
 or a Tur authority, like an historian or a biographer
