Thanks to Bert and Kim for the suggestions . Actually, I was not looking for a way to pause the script, but to slow down the animation. Bert's suggestion about changing the tick rate on the "script clock" was a revelation. Who knew? (obviously not me). And actually, Kim's idea of adding a blank "something" to the holder was one I came up with out of desperation in class yesterday. I suggested it aloud and within about three minutes, one of my 6th-graders had done it!
All of which makes me wish that we had some serious documentation for Squeak. I know that it's asking the impossible for an open-source project, where most people volunteer their time. Perhaps if we had a wiki for newbies, a la some Linux distros (see http://www.ubuntulinux.org/wiki/FrontPage for an example), it would at least serve as a central repository for stuff like this. I realize there already is a Squeak wiki, but most of it seems aimed at a more technical audience than perhaps use Squeak for eToys.

Well, in the powerful ideas book this technique is shown in project 6 (page 32 in the english version). Even if you're not using it in class it's really worthwhile to get a copy and run these projects for your own education.
