In addition to tab/shift-tab you can also use ⌘G/⇧⌘G.
The main reason that ⌃S is not among the keys you can use is that the search box is a standard Cocoa text field and a frustrating amount of custom code is required to grab the ⌃S/⌃⇧S keys (to the best of my knowledge) — so given that ⌘G is already standard, this will have to do for now.
