I ran into something similar about a month ago, I believe that it was 
caused by IC formatting certain fields with [currency]  Here's a bit of my 
code that I used to get around it.

[seti tmpdiscountsubtotal][subtotal noformat=1][/seti]
[perl arg=scratch]
   $_ = $Safe{'scratch'}{'tmpsubtotal'} - 
$Safe{'scratch'}{'tmpdiscountsubtotal'};
   $Safe{'scratch'}{'subtotaldiscount'} = $_;
   return '';
[/perl]
[currency][scratch subtotaldiscount][/currency]

note the "noformat" attribute to strip the currency format off the 
numbers.  And I also tried all sorts of variations with using the IC tags, 
but found that in the end, the only way I was able to get it working right 
(IE The way I wanted) was by using the perl style syntax in the page.
