Help with analysing data

I have submitted a questionnaire indicating respondants to give their ranking in accordance to their preferred weighting - for example if they gave it a ranking of 1 it means that they want the most weighting, and 12 the least.

How can I analyse the results of such data? What tests should be used.
The question relates to weighting of components in a pricing system.

What features would you like to include in the pricing system? Write the ranking of your preference next to each item (from 1 to 12)

Colour 1
Type 2
Imported/Local 3
Quality (high/low) 4
