Put double quotes around it as in

-thumbnail "100x100^"

The error message indicates that it read the geometry argument correctly but didn't understand it. I checked the Changelog and the ^ wasn't added until version 6.3.8-2 so you'll have to upgrade your version of IM to get the functionality of ^ in geometry specs.
