You are right. The local keymap for *scratch* buffer defined ESC. After
I unset it, I ran

(key-binding "\e")

and the answer was nil.

After that, I entered

> (let ((input-mode (current-input-mode)))
>    (setcar (nthcdr 3 input-mode) ?\e)	; QUIT = ESC
>    (set-input-mode input-mode))

replacing (set-input-mode input-mode) with (apply 'set-input-mode
input-mode), but pressing ESC when the minibuffer is active (e.g.,
during entering a filename) still has no effect. After I said

(global-set-key "\e" 'keyboard-quit)

pressing ESC in the scratch buffer causes the word "Quit" to appear in
the minibuffer, but pressing ESC in the minibuffer still has no effect.
