Replying to my own post... Not cool :-) Heh. *blush* I just looked at the WML option tag ( http://www.w3schools.com/wap/tag_option.asp) and there is no 'selected' attribute so hence it is not available in the Tapestry WML component.
Looks like ivalue is used to select the option in the WML select ( http://www.w3schools.com/wap/tag_select.asp). Try an informal parameter in the select component to set the ivalue.
