Ah, but this appears to be expected behaviour:

    (defcustom SYMBOL STANDARD DOC &rest ARGS)

    [...]
    STANDARD is an expression specifying the variable's standard
    value.  It should not be quoted.  It is evaluated once by
    `defcustom', and the value is assigned to SYMBOL if the variable
    is unbound.  The expression itself is also stored, so that
    Customize can re-evaluate it later to get the standard value.
    DOC is the variable documentation.

Compare what happens with:

(defcustom time (current-time)
  "the time"
  :type '(list integer))

So perhaps the thing to be fixed is that describe-variable should say
"Standard value" rather than "Original value".
