Confusion with yarn weight and requested gauge for scarf pattern

Hey all,
I'm very new to knitting, and I'm making a scarf from a pattern that can be found here:
http://www.freevintageknitting.com/scarf-pattern/botany2/scarf

I appologize if this is just a dumb mistake, but the specific part that confuses me is:
"MATERIALS: BOTANY CLASSIC SPORT, 1 oz. skeins,
Color A-5 skeins Color B-5 skeins
KNITTING NEEDLES: 1 pair "Boye" Non-Inflammable Needles, Size 6 -OR SIZE YOU REQUIRE TO KNIT TO GAUGE GIVEN BELOW.

GAUGE: 10 sts = 1 inch 29 rows = 4 inches"

I was under the impression that 10 spi was more like a super fine or lace weight than a sport size, yet the pattern calls for Botany Classic Sport. DId they mean 10 sts per 4 inches? Can I make the gauge that small for sport weight, even with the smallest size needles? Which yarn should I use?

Thanks,
