ZSM 7 SP1 ir3 hp3 Variables in Pre or Post scripts fail with 'ERROR - Failed processing software package'

When using variables on other places in the package the Software Package distributions work. 

Defining the variables in the TED.CFG  or Subscriber does not resolve the symptom. 

This functionality worked in previous code. 
 
Steps to duplicate: 
  
1)  Start C1 (containing the latest ZSM snapins). 
2)  Right click "Server Software Packages"  and select "New Package".   
3)  Click Next, enter a package name (e.g. test) and a file name (test.spk; file needs to be on the server.), click on "Finish".  
4)  Right click on the package and select Properties.  Click on the "Variables"  tab. 
5)  Click on "Add"  and add a Variable: TESTVAR  and a Value: sys:/system/edit  and click on "OK"  twice.  
6)  Right click on the package and select "New Component".   Give it a name (e.g. testcomp).  
7)  Right click on the newly created component and select properties.  
8)  Select the tab "Pre-Installation" or "Post-Installation"  and select script.  
9)  Click on "Add".  Click on the right pane and enter: load %TESTVAR%  . 
10)  Click on "OK".   
11)  Right click on the package and select "Compile",  c lick "Next",  enter a filename (with .cpk and on the server), click on "Finish".  
12)  In C1 select the OU where the Distributor is.  
13)  Create a new TED Distribution.  Enter Name and the Distributor.  Also check "Define Additional properties".  
14)  Under Channel select the channel to be used.  
15)  Under the "Type"  tab select type "Software Package",  select "Add",  select the test CPK  created.  
16)  Under schedule, check both boxes and for schedule type select "Run Immediately".  
17)  Approve certificates being sent.  
18)  Right click the distributor and select "Refresh Distributor".  The packet will start being distributed.
