Normally I'm looking at six or seven Googles and five or six Y! for each Ask I see - so I thought this either a coincidence or some kind of update / test where I was suddenly ranking very well in Ask.
Something's up, either it's some kind of "funny business" going on or their user base is increasing.
Are those phrases seasonal?
Are those phrases related to current events?
Did Ask feature you somewhere in their search?
Assuming you didn't lose ranking positions, it's likely that kind of anomaly was due to a fluctuation caused by external reasons. Certainly not in any way due to an increase in usage of Ask. From ten visitors to a thousand then back again? That's an externally influenced fluctuation.
My Ask traffic has remained the same, btw.
Sometimes above the normal search results a relevant feed appears. Very handy.
