Yes, it is possible to specify a specific version of asset in changeset. 
though this is not supported by Change-set editor at the moment, you 
have to edit the content of change-set xml file manually. For example, 
below is generated by change-set editor:

<change-set xmlns='http://drools.org/drools-5.0/change-set'
     xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
     xs:schemaLocation='http://drools.org/drools-5.0/change-set 
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd'

     <add>
          <resource 
source='http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/source' 
type='DRL' />
     </add>
</change-set>

If you want to use a specific version of asset "sss", what you need to 
do is to modify the source URL, make it pointing to the specific version 
of the asset source. eg:

          <resource 
source='http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/versions/2/source' 
type='DRL' />

This is to get version 2 of asset "sss" source.
