Actually it's easier than it appears. All you need to do is set the height of each UL inside of the list-wrap to be the same height - here is the demo, and the extra css needed:
#example-one .list-wrap ul { height: 320px; }
Just change the ID (#example-one) to match your organic tabs wrapper.
Not to be difficult, but the "whole point" of organic tabs is the height adjustment thing. It's probably not a good fit if you don't need that. You'd just write some simple JS to hide/show divs with fixed heights.
