You want to use the [#] suffix to get the number of instances of an 
attribute - so

if (&reply:Framed-IP-Address[#] > 1) { ....

Why use Tmp-String-0 - just use Tmp-IP-Address-0 to keep the data type 
consistent - then there won't be any casting issues.

Of, since you're putting the result you want in the control list, you 
can just use Framed-IP-Address- so

update control { &Framed-IP-Address := &reply:Framed-IP-Address[0] }
