Your field is transparent so setting the color won't show up. Just set  
the opaque flag to true:

  if (pData contains "foo") then
     set the backgroundcolor of field 1 of me to "red"
     set the opaque of field 1 of me to true
  else
     set the opaque of field 1 of me to false
  end if

I tried this in your test stack in the bug report and it worked.
