I won't defend the method by which they arrived at the standard, but
I think they arrived at a good standard (or are arriving at if it's
still in draft form...)

I just looked though the catalog at www.x9.org and I didn't see it.
I did find mention that the standard has gone to ballet. (In fact,
I know that it has done so at least once -- Eli Biham and Lars
Knudsen's paper
(http://www.cs.technion.ac.il/users/wwwb/cgi-bin/tr-get.cgi/1998/CS/CS0928.ps)
on the weakness of the CBCM mode came out shortly before X9.52 came to ballet
initially, delaying the specification.
You should be able to buy a copy of the standard a few weeks after it
passes ballet...

Guidance the FIPS 140-1 treatment of 3DES is at:
http://csrc.nist.gov/cryptval/140-1/1401ig-4.htm#9tripleDES

?
Before things become standards, they are just good ideas. Triple DES is
widely used, despite the fact that there is no absolute standard. The
draft standard, itself, is actually quite straight forward... Nothing
really interesting about it, aside from ANSI's blessing.
NIST does the "we'll just refer to another standard and call it ours"
thing a fair bit... Look at FIPS 186-1: The RSA signature scheme accepted
is the one specified in ANSI X9.31.
