Hi. I made a couple changes to your example and got it to work both
with 2.7 and 2.8:

 - remove the select control
 - activate the modify control after it is added to the map
 - programmatically select the feature through the modify feature
control's internal select feature control
 - add a hack to fool the select feature control's feature handler
(related to <http://trac.openlayers.org/ticket/2204>).

Also note that ModifyFeature in trunk includes the property
"standalone", which may just accommodate your case. See
<http://dev.openlayers.org/apidocs/files/OpenLayers/Control/ModifyFeature-js.html#OpenLayers.Control.ModifyFeature.standalone>
