[ic] not working: $Config->{PriceField} = 'other_price';

[Grant]

I'm trying to change prices on the fly like this:

[fly-list code=sku1]
   [perl no_return=1]
      $Config->{PriceField} = 'other_price';
   [/perl]
   [item-price]
[/fly-list]

But the change isn't being reflected in [item-price].  Does anyone
know what could be wrong?
