The rasboras eat shrimp too, in fact any fish that is big enough will have a go at shrimp with the exception of algae eating fish. Algae eaters will eat dead shrimp but don't actively hunt the live ones
There is another option, rather than getting small shrimp, how about some of the bigger shrimp (Macrobrachium species) or even small freshwater crayfish (aka crawfish). It depends on which country you live in but Macrobrachium are found in most tropical areas around the world and there are freshwater crayfish in virtually every country with freshwater creeks or rivers.
Even the common glass or ghost shrimp would probably be ok and are cheap, you might even be able to collect your own if you find a clean creek or river. They hide in the grass growing in the water along the side of the bank.

Potential tank mates for tiger barbs and scissortail rasboras include: big tetras like Congo Tetras, African Longfin Tetras, any barbs that are as big as the tigers or bigger, Filament barbs, Golden Barbs, Giant Danios. Maybe blue, gold, pearl or kissing gouramis. Bumblebee or Hoplosternum catfish, but make sure they have something to hide under during the day.
