As far as I can tell the thing you are missing is that the [if scratch 
testme] and [scratch testme] will not be evaluated until after the loop 
is complete, so while the scratch is set in the loop ($Tag->tmp(...)) 
the evaluation of the scratch is doen after the loop and will evaluate 
against the last value you set.  I don't know what you're actually 
setting it to, but I'd venture to guess that the last value returns 
false for the purposes of the [if scratch ...] test.
