Alan Judge bagged the winner against Carlisle and is refusing to give up hope of a play-off places.
"The games are coming thick an fast and the sign of a good team is when you can keep winning or at least make sure you don't lose," he told his club's official website.
"We're on a good roll at the minute and that's five unbeaten so we'll give everything we can until it's not possible."
Kevin Lisbie is poised to return to the Leyton Orient starting line-up.
The veteran striker came on as a substitute against Bournemouth on Saturday after two months out with a hamstring injury and scored the third goal in Orient's 3-1 win.
Fellow forward Shaun Batt, who has extended his loan spell from Millwall until the end of the season, will be checked over after missing out at the weekend with a tight hamstring.
Should Batt return to the squad he will take the place of midfielder Anthony Griffith, who on Monday rejoined his former club Port Vale on loan for the rest of the campaign.
