Techs after time expires with tied game

[Rich1]

SITUATION: Had one of those crazy situations this weekend. 4th qtr ends with a score of 68 - 68. Team A's coach is throwing a fit about some late calls. Had already been warned earlier in the game and given more than enough leeway during regular time. I tell the coach that we understand his position but its in the past now. He continues fussing, I inform him that his concerns had been "asked and answered" so the topic was now closed, he continues to complain and earns a tech.

QUESTION: When is the tech administered? My interpretation is that since the game is tied, we start OT with two shots for the tech and a throw in for team B - we would only shoot the two shots if the score was NOT tied to determine IF overtime is needed. Several of my colleagues (and Team B's coach) say the techs are an extension of the fourth qtr and should be administered to see if OT is needed - make one game over, miss both go to OT.

I know I did it right but want to get confirmation from the group here.
