Who has the worst match bowling figures in test cricket history?

Imran Tahir finished a test match with bowling figures of 0-260 (zero wickets for 260 runs) in 2012:

Worst. Bowling. Figures. Ever!
Sydney Morning Herald | November 25, 2012

South African spinner Imran Tahir went from bad to worse; all-time worst, in fact. Tahir has recorded the worst bowling figures in a Test match. The legspinner's match figures of 0-260 against Australia in the second Test in Adelaide surpassed the previous worst ever by Pakistan's Khan Mohammad. Khan posted figures of 0-259 against the West Indies in 1958 - all from one innings.

Depends on how you define "worst." There have been 37 instances of a bowler conceding MORE than Imran Tahir's 260 runs in a match (plus two more bowlers who also conceded exactly 260 runs), however all 39 of those players took at least 1 wicket. If you define "worst" as "most runs conceded without taking a wicket," then Tahir is the answer. However, if you define "worst" as "most runs conceded in a match regardless of numbers of wickets taken," then the West Indian spinner OC "Tommy" Scott is the answer, having conceded 374 runs on his way to match figures of 105.2 overs bowled, 13 maidens, 9 wickets for 374 runs against England in 1930.
