The Scottish champions were looking for a victory at McDiarmid Park to keep alive their hopes of recording 100 points for the 2013/14 season.
Nevertheless, Lennon was looking forward to celebrating a successful season which has seen the Glasgow giants score on no less than 99 occasions ahead of the home meeting with Dundee United on Sunday.
"Not really. You set yourself little targets and it would have been a nice milestone,‚ÄĚ said Lennon when asked if he was disappointed not to reach 100 points.
"We should have done because we were 3-1 up with 10 minutes to go, but we have scored 99 goals, we are one short for 100 and that would be nice to finish the season off with that.
"I am really looking forward to Sunday. The lads haven't had the opportunity to celebrate the title win so to get the trophy at home will be a special day and I want them to finish the season on a high.
"It was a game of two halves tonight. We were poor in the first half but very good in the second."
