Ferguson was steaming after Beck turned down Wayne Rooney's penalty appeal at Tottenham.
And his mood worsened as Clint Dempsey hit a 92nd-minute leveller.
Fergie said: "The linesman on that side of the pitch didn't give us a thing all day. For me, it was a poor performance by him. Why he never saw the penalty kick from Wayne Rooney, some other decisions, I don't know.
"He had a shocking game again and I'm disappointed in his performance, I really am."
Beck incurred Fergie's wrath when he failed to flag for offside against Chelsea striker Drogba as he scored the Blues' winner in their 2-1 victory over United at Old Trafford in April 2010.
