Since [item-price] is not a database value nor a variable value,
there is not direct accessor.

(By the way, this is one of the most common errors I see on
the list. You can't just invent things like [if item-price > 0],
but people seem to think you ought to. I don't quite know what
to do about this; suggestions are welcome.)

Usually, with price the problem is two-fold:

	1. Value may be 0.00, which is true to Perl, so
	[if-field price] will not work even if you are using
	just simple pricing.

	2. If using the output of the [item-price] tag, currency
	formatting can mess you up.

Here is the canonical way:

[if type=explicit compare="[calc][item-price noformat=1] > 0[/calc]"]
...
[/if]

You can use backticks, i.e. `[item-price noformat=1] > 0`
works instead.
