TBH, the simplest thing is to *not* use "foreach".  I'd guess that the Cisco-
AVPair attributes come in the same order all the time.  So you can just rely on
that.  e.g.
if (Cisco-AVPair[0] =~ /^dhcp-option=/) {
      update request {
      	Tmp-Integer-0 := "%{unpack:&Cisco-AVPair[0] 12
integer}"
      }
  }
That will get you the binary data (4 octets) into Tmp-Integer-0.
Thank you Alan. It works. AVPs always come in the same order.  The unpacked data looks correctly. 
The last modest question yet - how the get the rest of the attribute (string following the TLV binary code)?
Keep using %{unpack: ... }
