Wikipedia has an article listing 81 B727-100 and 419 B727-200 aircraft still in airline service - referencing the numbers to an article by Flight international called "World Airliner Census" dated 19-25 August 2008.
Since I don't subscribe, I can't comment on the veracity of the information.
The Wiki article list the following carriers with several aircraft - these numbers seem to be close
FedEx - 86
Astar Air Cargo - 25
Capital Cargo International Airlines - 13 - Maybe 14 - being purchased by ABX Holdings - parent of ABX
Kelowna Flightcraft Air Charter - 13 - maybe 15
Cargojet Airways - 12
Transmile Air Services - 5 or 6
The article also list some closed airlines
Champion Air - 16 - ceased operations 31 May 2008
Kitty Hawk Aircargo - 16 - ceased operations in Jan 2008
Other carriers who may have the B727 in inventory - Syrian Arab Airlines (2), Air Libya (2), Varig Logistica (3), TAF Linhas Aereas (1), Total Linhas Aereas (4), Interair South Africa (3), Asia Pacific Airlines (3), Amerijet International (10), Aerogal (1),
DHL owns the some of the Transmile aircraft according to several sources, and additional B727 aircraft based in Panama (4), Venezuela (3), Saudia Arabia / Bahrain (6), South Africa (1 ?), Australia (1),
UPS website list they own 2 B727 aircraft which are leased to other carrier(s)
You can do some more research on this list - scroll down toward the bottom to see the active registrations by airline - and the subsequent pages
Edit - looks like 8 still in Iran, and don't for get Con Air - the two B727's owned by the US Marshall's Service flown as JPATS. The Mexico Air Force has several, as quite a few nations around the world.
Don't forget there are more than two dozen in private hands, with winglets, stage 3 engines and expensive interiors.
Jack Roush has two nice ones, but not high end executive, flying mostly for NASCAR charters.
