It looks like both of these sample pages have other javascript errors that aren't related to Validation Tooltips that are probably causing the Validation Tooltips to not run properly.
I'll try using WebAssist Site Import to get a copy of the pages and scripts and see if I can debug and get them working, but I'd start by looking at the javascript errors on those pages and trying to get them corrected. My guess is that correcting the javascript errors will fix the tool tips, but I'd have to test that theory to be sure.
