Swift r2748 adds a SWIFT_EXTRA_INFO environment setting, that you can use 
like this:

  <pool handle="localhost">
    <gridftp  url="local://localhost" />
    <execution provider="local" />
    <workdirectory >/var/tmp</workdirectory>
    <profile namespace="karajan" key="jobThrottle">0</profile>
<profile namespace="env" key="SWIFT_EXTRA_INFO">echo monkey foo</profile>
  </pool>

to get a line like this in your wrapper log:

EXTRAINFO=monkey foo

See if you can get the version information you want passed back through 
that mechanism.
