Hm, that's odd. I wonder what it could have been. The only losses I ever had with Tiger Barbs was due to a Red Tail Shark and teenage aggression.
However, one thing which may help: Tiger Barbs are the only fish I have ever seen not be able to adapt to a high pH. I noticed my pH dropping once and put in a chunk of Texas Holey rock (Limestone). The pH raised over the next week or so (very gradually) and as it did the fish were fine until the pH hit 7.8. They then started to have trouble swimming straight. All listed info I can find on TBs listed 8.0 as within their range... I disagree! This maybe wasn't the case with your tank, but from my experience TBs really react to pH more than anything else I've kept. Taking the rock out fixed them.
