Workflow Escalation Problem

Question

Hello all,
I need to initiate a criteria workflow with 2 steps and each step having 1 user.
I want a situation where a workflow is being initiated and it goes to step1 user then it will wait for a specific time (say 5 mins) for that user to approve. If that user doesn't approve it within that specific time it should automatically escalate to 2nd step user.
I have created the steps and i am using the following script in exit criteria of step 1
<$if parseDate(wfCurrentGet("lastEntryTs")) < parseDate(dateCurrent()-(5*60*1000))$>
     <$wfSet("wfJumpName", "jump1")$>
     <$wfSet("wfJumpTargetStep", wfCurrentStep(1))$>
     <$wfSet("wfJumpEntryNotifyOff", "0")$>
<$endif$>
the workflow is coming to step1 user but the problem is it is not being escalated to step 2 after 5 mins.
I have tried that script in update criteria of step1 and also in entry criteria of step2 but it doesn't work.
I have tried setting no of approvals required in step1 to zero. but no progress after that also.
I have tried the condition with check in date also and my script is as follows. But it doesn't work.
<$if parseDate(dCreateDate) < parseDate(dateCurrent()-(5*60*1000))$>
     <$wfSet("wfJumpName", "jump2")$>
     <$wfSet("wfJumpTargetStep", wfCurrentStep(1))$>
     <$wfSet("wfJumpEntryNotifyOff", "0")$>
<$endif$>
Please help me.

There is one more thing I did not observe last time:
i am using the following script in exit criteria of step 1Escalation code must be in update event - exit is executed only if an item is approved by sufficient number of reviewers and processes to the next step. Actually, workflow manual (at least in 10g) contains an example of escalation workflow.
