Rutherford, who claimed gold on Super Saturday in the Olympic Park, leapt to 7.99m to finish ahead of Tomlinson, who recorded a best effort of 7.69m.
"It wasn't a bad performance," said Rutherford. "I had a few problems at the start but I gave it everything in the last jump and, while I was really keen to get over 8m, 7.99m I will take. Overall I'm pretty pleased."
Christophe Lemaitre won the men's 150m in 14.90 seconds with Great Britain’s Dwain Chambers in fourth place, while British compatriot Andy Turner also had a frustrating afternoon as he pulled up in the 200m hurdles.
In the women's event, the USA's Allyson Felix powered to victory while the respective winners of the 100m races were veteran Kim Collins and Margaret Adeoye, who won in 11.58 seconds.
