Why are you trying to do this?
If you share your goal, we might be able to help you with a workaround
or alternate strategy.
For example, if you use a hostname in the "Address" field, your
authority will look it up, add the IPv4 to its descriptor, and then
other authorities, relays, and clients will use that address.
(After the network has bootstrapped using the original address.)

It is the implemented behaviour, and has been since at least 2006
(tor-0.1.2.2-alpha). The code responsible is:
while (smartlist_len(items)) {
char *flag = smartlist_get(items, 0);
if (TOR_ISDIGIT(flag[0]))
break;
Which means that only IPv4 addresses are guaranteed to work here.

The "Address" torrc option takes a hostname, as do some other options
(I think the HiddenServicePort target is another.)
Thanks for the bug report, we'll fix the man page:
