Yes. TT uses stringwise comparison in an attempt to Do The Right Thing
for most of the people, most of the time.
Unfortunately, when you really do want numerical comparison, there is no
easy way to do it. You have to jump through a hoop or two.
One possible way is like this:
[% USE pad2 = format('%02d') %]
[% 'selected' IF ymd.1 == pad2(mon) %]
You can wrap this up in a MACRO if you like:
[% MACRO check_month(date, month)
GET date.split('-').1 == pad2(month) ? 1 : 0
-%]
[% 'selected' IF check_month(date, month) %]
Or you could implement your own numerical comparison subroutine in Perl
and bind it to a variable.
$tt->process($template, { equals => sub { $_[0] == $_[1] } });
[% 'selected' IF equals(ymd.1, month) %]
Bit of a kludge I'm afraid. There probably should be some easier way to
do this. Suggestions welcome...

Yes, this is a limitation in Pipermail which Mailman uses to archive the
mailing list. A search facility seems to be very high on everyone's
wishlist.

Yes, the FAQ is abysmal. I spent a marathon 6 weeks writing all the docs
for TT2 and the FAQ came right at the end of that process when my brain
was jelly and spirit flagging. Needless to say, I didn't get very far
into writing it and haven't really gone back to it since.
So, if there is anyone out there who wants to take responsibility for the
FAQ, I'd be most happy to hand it over.
