F&R can be told to search the recently opened documents list
but it doesn't currently search (or list) the apps recently run outside of find&run, or have the ability to score them differently;
people have requested and i think it's a good idea, to be able to treat programs recently executed outside of F&R specially (since they are likely to be things that people want to run again.
a related feature might be the ability to add scoring heuristics based on date of last access, etc.
