Cream together butter and sugars, then blend until light and fluffy. Add pumpkin pie mix, eggs, water, vanilla and orange zest to creamed butter and sugar mixture. In a separate bowl, mix flour, soda and salt. Add in stages to the wet mixture. Fold in the butterscotch chips and pecan pieces.
Chill dough at least 2 hours or until firm.
When ready to bake place rounded teaspoons of dough on ungreased cookie sheet. Bake in a pre-heated oven at 375F for 10 - 12 minutes.
