Ok, there's been discussion, including, I think, on the wiki web page, that syslinux is not correct. At any rate, after enough experimentation, I have a working install on a USB key. The procedure is:
Using fdisk, partition your key: one partition, VFAT (type b, and toggle the bootable flag), about 9M or 10M, and a second partition big enough to hold a DVD. That should be type 83 (Linux native).
mkfs -t vfat <the DOS partition) mkfs <the Linux partition
liveCD-iso-to-disk <.iso, w/ full path> /dev/<USB DOS partition> mount <USB Linux partition> /mnt cp <CentOS.iso> /mnt/
You're done. You do have to tell it "install from hard disk", and then point it to the Linux partition.
I just did this and tested it (or at least as far as the "searching for existing CentOS installations).

Following these instructions, what iso do I use for the livecd-iso-to-disk step?

Not sure what's going on there. liveCD-iso-to-disk dd's (or whatever) a bootable vfat (or is it fat?) filesystem, and *only* enough to boot the installer. The full DVD .iso goes in the other partition, which you've mkfs'd, just as a .iso.

Maybe I'm using the wrong script. I have livecd-iso-to-disk from the livecd-tools-014-8 package. Is liveCD-iso-to-disk a different script?

Odd. I don't understand that... you *did* make the filesystem type b, right, and bootable with fdisk? And then format it vfat?
Btw, dunno if you missed it, but here's a full script to do this:
#!/bin/bash
if [[ $# < 2 ]]; then echo "usage: $0 <devname> <path/to/install.iso>" echo " Example: $0 sdb /scratch/CentOS-5.4-bin-DVD.iso" echo " Note: you must install livecd-tools before running this." exit fi

I used your script (after removing the '-n' from sfdisk) and got the same results. Unless you have a better idea, I think I'm going to try putting the boot.iso on the first partition and see what happens. Unfortunately, I won't be able to test until tonight since I don't have a system here that will boot from a flash drive.

Ok. Sorry, no clues as to why it's not working for you.

I was able to successfully install from an 8GB USB flash drive (4GB is not quite big enough, even for i386) created with this procedure:
Create a 10M DOS partition and make it active Create Linux partition using the rest of the drive
mkfs -t vfat <the DOS partition> mkfs <the Linux partition>
liveCD-iso-to-disk <boot.iso> /dev/<USB DOS partition> mount <USB Linux partition> /mnt rsync --progress <CentOS.iso> /mnt/
You can get the boot.iso by loop-mounting the CentOS iso and pulling it out of the /os/i386/images directory, or grab it from one of the mirrors (the mirror links on the CentOS site link directly to the install isos, so you'll have to browse up a few directories and then go back down to find the images directory).
(I replaced the 'cp' command with 'rsync' here because I hate having a copy run for 10 minutes with no progress indication :)
