Interesting, but not without precedent...

My inclination here is to recommend one of a couple solutions, somewhat dependent on how much water is in the frame.
- If it's a small amount, you can probably lay the frame out in the sun for a full day or two and most of it will evaporate and vent out from whence it came.
- If it's a larger amount and you can conclusively determine which tube it's in, a machine shop or frame builder should be able to add a vent hole in the bottom brackets and/or head tube to allow the water to flow out of the frame. Again, you'd want to let the frame sit out in the sun so that the residual moisture can evaporate before you start to put it back together. If you're pretty handy with machine tools you might be able to create a vent hole in the front eccentric bottom bracket, but the rear bottom bracket and head tube cavities would be a bit more problematic for the average home wrench with typical home shop tools.
After that, so long as the frame still sounds solid I wouldn't worry about it unless there were other signs of frame weakness or decay at the welds or along the tubes. I also wouldn't bother putting any frame saver / varnishes / Boeshield in the frame. Even if that stuff did work -- which is not really clear -- it wouldn't do much for your frame at this point. On the bright side, a Sovereign of that vintage has pretty robust steel tubing.
