Multiple products sort by HELP !!!!!!!!!!

[kian101]

hi need to know is it possible to get the products to sort  by two factors instead of just one i.e  price , default ect

need the products to be first ordered by price ( lowest to highest )and then ordered by  if they are sold or not  life follows

product a : price-300
product b : price-400
product c : price-300 sold
product d : price-450 sold

needs to work as shown above as the sold products still need to be displayed , however should be ordered at the bottom of the page


any help would be much appreciated many thanks  ki
