Just to complicate matters, each International Test side has a different 'unlucky' number, for different reasons. 87 is traditionally the Australian 'unlucky number' because they have apparently lost most Test wickets, at that score, either as individual batsmen, or as a team score.
111 is traditionally accepted as the 'unlucky' England score for the reasons oulined in an earlier post, in relation to Horation Nelson. Triple Nelson (333) was the score at which Graham Gooch was out, in highest ever Test score. If David Shephard was (Umpire) was officiating in a mtach where any of the 'Nelson Scores' appeared on the scoreboard, he would hop about on one leg, until the score moved on, supposedlyt o break the curse of the 'Nelson Score.' Very amusing to watch !!!
If you are happy to accept 87 as the definitive answer for your frelevant purpose, I'll not bother explaining the other Test sides 'unlucky numbers'.
