Hi Jason,

I see a few people have had a stab at this, but I have a feeling I know 
what you really meant ;-)

try this:

<tal:i repeat="group groups/existing/high">
   <option tal:define="event sp_info/?group/common_name"
           tal:content="group"
           tal:attributes="onmouseover string:doTooltip(event,'$event')"
           onmouseout="hideTip()">
   </option>
</tal:i>

cheers,

Chris
