Use a triply linked structure as opposed to an array when implementing a priority list using a heapordered binary tree. Each component will require three links: two to move up the tree and one to move down it. Even if the utmost size of the priority queue is unknown at the outset, your implementation should still ensure logarithmic running times for each action.
