The West Australian posted a final round 69 to finish T5 at the Albatross Golf Resort, matching his effort at the Rocco Forte event in May.
While he was fourth at the World Super 6 event in Perth in February that tournament is a modified matchplay event.
Scrivener’s 68-69 finish was among the best scoring of the weekend, only four players going lower Saturday and six on Sunday.
South Africa’s Haydn Porteous was one who matched Scrivener Sunday, his 3-under final round enough to overtake 54-hole leader Lee Slattery of England and hand him a second European Tour victory.
The 23-year-old finished 13-under for the four days, two ahead of Slattery who was alone in second after a 1-over 73, one ahead of third placed Tom Lewis and Pontus Widegren.
Scrivener was part of a four way tie for fifth built predominantly around a brilliant Saturday in trying conditions.
Heavy rains flooded the course Friday afternoon and forced a suspension of play when Scrivener had played just three holes of his second round.
Returning Saturday for a marathon 33-hole day Scrivener managed seven birdies against just two dropped shots to move well up the standings.
He rolled that form into his early play Sunday and was 5-under through 10 holes to be on the edge of contention but dropped shots at the 11th and 13th killed his momentum.
Scrivener was the best of the Australians in Prague, Nick Cullen finishing even par and T43 with Richard Green a shot further back and T50.
At the top of the leaderboard is was an ecstatic Porteous who hoisted the trophy, the young South African one of a promising group from that nation plying their trade in Europe this year.
After winning the Joburg Open in his home country last year Porteous struggled with his game but a first top 10 of the year in Denmark last week suggested things were beginning to turn.
"It's been a really torrid time through the last eight, nine months and I've really started doing the right things and slowly but surely the golf has got a little bit better," he said.
"To get my second European Tour win under the belt just feels amazing.”
Porteous said he had struggled with graduating to the world’s second biggest circuit but had matured over the last 18 months.
"When you start playing on the European Tour you start to lose yourself, you lose how you got out here in the first place and to then find yourself again and do the things you do to normally get on the Tour is key,” he said.
"It's just one tournament at a time, one shot at a time and just make sure I do the right things and be professional in the way I do everything.
“I'm sure this evening's probably not going to be the most professional moment of my life but there's nothing wrong with having a bit of celebration."
