I think it's easier to code, read, maintain in awk:

Code:
awk -F = '
    match( $1, /"(-*[0-9]+)"/, hit ) {
        gsub( "\";", ";" hit[1] "\";", p );
        next;
    }
    {
        if( p )
            print p;
        p = $0;
    }

    END {
        if( p )
            print p;
    }
' input-file >output-file
