The numbers you gave appear to be "life expectancy at birth" for males and females.
There were 39,630 live births in Singapore in 2011. Their data does not seem to have any info on how many of those births were male or female children, so there is no way from it to get a ratio.
That said, CIA factbook say 107 male births per 100(to convert it to compare with the articles claims)

Nationmaster says closer to 108 per 100

Either way, not quite the articles claimed disparity of 120, 130, etc.
China seems to be at about 113/100. For comparison the US and the UK at 105/100, which seems to be about the norm, though African countries seem to drop lower.
It is still an issue. For china, that extra 8 boys/100 could translate to an extra 50 million males, if the trend continues for all future generations. That's a lot of guys who may want to find mates and be unable, along with all the social stigmas attached. That said, wouldn't it be great if we could somehow translate this into a greater respect for women in those societies? Rare items are usually considered more valuable. The trick would be to have it become respect/power for women, rather than just a new reason to control them.
Although, if you dig into their links, there is one that seems to indicate that in 2011, there are 972 male singapooreans to every 1000 females
