The Pesukim of Malchiyos, Zichronos and Shofaros

In the rosh hashana mussaf, we read 10 pesukim from Tanach for each section mentioned above. We read them in the following order: Torah, Kesuvim, then Nevi'im. The question is obvious: Why does Kesuvim come before Nevi'im?

Readers of Nebach are probably thinking “Everyone knows the answer to that! Artscroll p. 454 gives 2 answers!”: We have to start with the torah because its so important, and then we follow the rule “ma'alin b'kodesh v'ein moridin” and do kesuvim, then navi. That answer sounds a little bit forced. Alternatively, since King David wrote most of the Kesuvim pesukim said in mussaf, and he came before the nevi'im, so we say kesuvim first.

While davening, I realized another, similar answer. Its quite simple and obvious. The pesukim in kesuvim are primarily about the past and the present. G-d has reigned, He reigns. He remembers people, past and present. The shofar blows. This is especially true if you just read the pesukim as they are in the machzor.

The pesukim from navi are primarily about the future. G-d will be King, G-d will remember us, the great Shofar will blow. This is obvious just from the quotes alone. Therefore, we first read the pesukim about past and present, and only then read the prophecies of the future.
