Correct call ?

[RefTip]

While watching our JV boys play the other day had this situation come up . Team A has the ball in their backcourt , Team B fouls Team A . While the official is reporting the foul he realizes ( table informs him ) that Team B has 6 players on the court. The official gives a Technical foul to team B and administers the technical foul first, then the FT's for the personal foul & then gives Team A the ball at half court .
I think the officials got confused on the sequence of administration but were they correct in giving the T because of 6 players ? ( The ball was already dead b/c of the personal foul on Team B ) .

Thanks for your input
