Having scored all Wales' points in the 10-5 win over Ireland, Thomas again got all 10 and the only try in Scotland.
Scotland's Six Nations hopes are left in ruins following last week's 60-0, 10-try hammering against England.
The Wales match was moved to Dunbar RFC because of a frozen pitch at the original venue, Meggetland Stadium.
We controlled the game and had the weather been better I feel we could have scored more points
Wales forwards coach Jason Lewis
Wales number eight Kylie Wilson won her 50th cap in the match.
"Our girls performed fantastically, especially in these conditions, which suited the Scottish style of play," said Wales forwards coach Jason Lewis.
"We controlled the game and had the weather been better I feel we could have scored more points.
"The team showed massive commitment and dedication to the task and this kind of performance sets us up well for our trip to France."
