org-collector is useful when you want to perform calculations on
properties *before* they are entered into a columnview type table.
Using org-collector a dblock like the following should work.

#+BEGIN: propview :cols (ITEM Quoted Sold (- Sold Quoted))
#+END:

The downside of org-collector is that it is not really part of org-mode,
and it doesn't have many of the nice features of columnview tables, like
the specification of column titles.  You can grab a copy of
org-collector.el from here
