You're giving it a regular expression and those semantics are hard to 
represent with regular expressions.  You could try this awk recipe:

gawk -F '[|]' '$1 != "results" { print $0; } $1 == "results" { 
split($3, quads, "[.]"); if (quads[4] >= 3 && quads[4] <= 25) print $0; 
}' old.nbe > new.nbe

It's a messy one-liner, but can be made prettier with newlines & 
indentation if this is going into a script.
