Because in the minibuffer's own keymap, which is different from the
"default" keymap, C-v is bound to scroll-up, the normal "default"
binding.

Of course, because C-r has the same binding in both keymaps, as does C-s.

C-letter keys shouldn't be bound to things, as a general rule, since
just about all of them are already bound to something. I do have a
similar problem, though, so I have C-\ remapped (which overrides
global-set-key, btw) to do C-s and C-] to do C-q. Here's the code that
does it:

;; until DAC fixes the #$% modems
(progn
  (setq keyboard-translate-table (make-string 128 1))
  (let ((i 0))
    (while (< i 128)
      (aset keyboard-translate-table i i)
      (setq i (1+ i)))))

; Cause C-s/C-q to be used for flow control.
; To get C-s, type C-\ (control-backslash)
; To get C-q, type C-] (control-right-bracket)
; These work by translating C-\ to C-S before Emacs looks at them, so they
; work even from inside I-search mode

(aset keyboard-translate-table ?\C-\\ ?\C-S)
(aset keyboard-translate-table ?\C-\] ?\C-Q)

Note that this will cause problems with telnet sessions with C-] being
the telnet escape character. Ah, well.
