How would I sort products within a category alphabetically instead of by popularity, low-to-high, or high-to-low?

Also why do my products get sorted randomly, instead of alphabetically, if the prices or popularities are identical....?

Originial post:
I'm having issues with the sort functionality of Znode within categories. I am entering new products and leaving their "Display Order" in Storefront Management as 500. I had assumed that when they were displayed they would be organized alphabetically if there is no difference between two items popularity or price.
I tried to address this issue by actually giving the Display Order field values for each product (to make it alphabetical) but it still is sorted randomly.
Even when i sort high to low or low to high it sorts my items randomly (most are the same price).

Question: Is there a way to have Znode sort things alphabetically instead of randomly if the popularity and/or the price is the same, as opposed to random sort?
