We have revamp whole discount package (#2006). The changes in this pull will remove all old table of catalog rule and cart rule but you did not change it manually.
You can normally take pull from master branch to upgrade it.
For right now , you can create a attribute for pretax, so when product will be created you can fill amount in this field.
We have fired two event in function collectTotals() ( calculate total amount of cart ) named as checkout.cart.collect.totals.before and checkout.cart.collect.totals.after.
