Aha. Turned out VERSION was coming from the parent. cmd.exe shows:
C:\Documents and Settings\bkw>echo %VERSION%
3.0.5.001


The real versions are:

The stand-alone version:
----------------
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\bkw>cd \aljex

C:\Aljex>.\zsh.exe
$P$Gecho $ZSH_VERSION
3.0.5-nt-sniff-4.1.1p2
$P$Gecho this is a test |read aa bb cc
$P$Gecho $aa $bb $cc
this is a test
$P$G
----------------


The cygwin version (just updated a minute ago):
----------------
bash-3.2$ zsh
$P$Gecho $ZSH_VERSION
4.3.2
$P$Gecho this is a test |read aa bb cc
$P$Gecho $aa $bb $cc
this is a test
$P$G
----------------


I can't explain why |read didn't work 20 minutes ago in the standalone 
version and does now, but I'll happily take it. :)
