I tried this:

                      <vdl:assign dpath="[i]" dvar="{k}">
                        <argument name="svar">
                        <sum>
                          <vdl:getfieldvalue var="{k}">
                            <argument name="path">
                              <concat>
                                <string>[</string>
                                <subtraction><variable>i</variable>
                                             <number>1</number>
                                </subtraction>
                                <string>]</string>
                              </concat>
                            </argument>
                          </vdl:getfieldvalue>  
                          <vdl:getfieldvalue var="{i}"/>
                        </sum>
                        </argument>
                      </vdl:assign>

which I think is pretty much what you said in the non-xml syntax.

But I get this:

$ swift aaaa.kml 
Swift V 0.0405
RunID: 7e7ozhoot4ha0
Execution failed:
        org.globus.cog.karajan.workflow.KarajanRuntimeException: Could not 
convert value to number: 1

so then I tried this instead:

                  <parallelFor name="$">
                    <vdl:getarrayfieldvalue path="" var="{r}"/>
                      <set names="$$, i">
                        <each items="{$}"/>
                      </set>
                      <vdl:assign dpath="[i]" dvar="{k}">
                        <argument name="svar">
                        <sum>
                          <vdl:getfieldvalue var="{k}">
                            <argument name="path">
                              <concat>
                                <string>[</string>
                                
<subtraction><getfieldvalue><variable>i</variabl
e></getfieldvalue>
                                             <number>1</number>
                                </subtraction>
                                <string>]</string>
                              </concat>
                            </argument>
                          </vdl:getfieldvalue>  
                          <vdl:getfieldvalue var="{i}"/>
                        </sum>
                        </argument>
                      </vdl:assign>
                  </parallelFor>


(adding in a getfieldvalue)

and when I run that it sits in an infinite loop (second today lucky me!) 

Bleugh.

full kml (edited from what came out of the compiler) is
