If you declare a user option as follows:

(defcustom bool-or-alist '((a . 4) (b . 7))
  "A made up option to illustrate a problem."
  :type '(choice boolean (alist :key-type symbol :value-type integer)))

And then run M-x customize-set-variable to change the value to t the
change fails with the message:

widget-prompt-value: Value does not match alist type

That :type specification works just fine with the customize UI using
customize-variable, it's just a problem with customize-set-variable.

I think the problem is that widget-choice-prompt-value figures which
branch of the choice the variable currenty has and then expects the new
type to be the same.

If you tag everything, then customize-set-variable works just fine:

(defcustom bool-or-alist '((a . 4) (b . 7))
  "A made up option to illustrate a problem."
  :type '(choice (const :tag "Yes" t)
                 (const :tag "No" nil)
                 (alist :tag "An alist"
                        :key-type symbol :value-type integer)))
