Saints in the shortlist

BBC reports on a TV show that's causing quite a stir in Georgia:

"A row has erupted in Georgia after a TV show called Top Ten Best Georgians included 18 saints in its shortlist ... A spokesman for the patriarch, who is the head of the Georgian Orthodox Church, said it was wrong to ask the public to put saints in rank order."

Are there canonical impediments to people favoring one saint over the other?
