Ahead of Australia's one-day global meeting with England - their first competitive match since the scandal-ridden tour - Paine asked Eoin Morgan if the teams could have a pre-match handshake on the field.
Defeat raised fresh questions about England's ability to win one-off, winner-takes-all fixtures following last year's Champions Trophy semi-final loss to Pakistan.
The Scots, sent into bat by England captain Eoin Morgan, lost two wickets in quick succession to be 107 for two off 15 overs. "We didn't play anywhere near our best, we were a bit rusty, but credit to Scotland".
"At the end, England didn't really finish the job".
"We have got to enjoy the occasion", he said. "I think it's going to be a good series".
For the tourists, time is running out on how to plan their World Cup defence - something scarcely helped by the enforced absences of Smith and Warner until a few weeks before the tournament begins.
"We set our stall out to be number one in the world and that's where we are, whether we were number one in this game or not, Scotland would still be delighted to win, it's not just because we are number one".
"The way we played, we didn't deserve to win it". As a 50-over nation, it's really exciting for them.' Asked if the Scotland defeat exposed some cracks in England's bowling attack, Agar continued: 'Potentially. "We didn't do enough to win".
Scotland's victory will send out a powerful message to the ICC, which voted to restrict the 2019 World Cup to 10 teams from the previous 14, which makes it far more hard for second-tier sides to qualify.
He added: "It does not take away what happened in Zimbabwe and everyone's feelings about the 10-team World Cup but this was a special day".
"To an extent I guess we have a psychological advantage because of the winter - it certainly gives us confidence that we can beat them". That is the bigger shop window rather than personal side of it.
Scotland's first win in worldwide cricket over England came in their first match since they were cruelly denied a place at next year's World Cup after a poor umpiring decision and rain saw them miss out in their final qualifier against the West Indies in Harare in March.
