Saturday's 1-0 win at Shrewsbury was not enough to take the Iron out of the relegation zone, but it did put them above Bury, Coventry and Colchester.
Doncaster won 2-1 at Colchester, who are now rock-bottom. David Cotterill opened things up for Doncaster but Magnus Okuonghae before Andy Bond put through his own goal.
Coventry, whose struggles this season have already cost Andy Thorn his job as manager, were beaten 2-0 at Tranmere.
The Wirral side secured all three points late in the day, with strikes from Jake Cassidy in the 79th minute and Andy Robinson sending them back to the top of the table.
They replace Notts County, who are a point worse off in second following their 2-2 draw at Oldham.
County - reduced to 10 men in the first half when Andre Boucaud was sent off - were 1-0 up shortly after the restart through Joss Labadie, but Latics debutant Matt Derbyshire swiftly equalised.
Robbie Simpson then missed a chance to put the home side in front by failing to convert a penalty and Jamal Campbell-Ryce restored the visitors' lead in the 82nd minute, only for another Oldham player making his bow, Jose Baxter, to draw things level again within three minutes.
That left the Latics in 20th on five points, one position above the Iron ahead of Tuesday's meeting between the two sides at Boundary Park.
Third-placed Stevenage also drew 2-2, coming from 2-0 down to take a point from their home match against Crewe.
Crawley are level on points with Stevenage in fourth after their 2-1 win at Preston.
Fifth-placed Walsall triumphed 2-1 at Portsmouth. Yeovil - the other side currently making up the top six - were beaten 1-0 at MK Dons through Charlie MacDonald`s goal.
Sheffield United's 1-1 draw with Bury at Bramall Lane saw them slip out of the play-off berths, with Nick Blackman and Peter Sweeney trading early goals.
Bournemouth and Hartlepool drew 1-1, while Carlisle and Swindon played out a 2-2 draw at Brunton Park.
