"Price:" text alignment in different browsers

I am having trouble with the following

when browsing with Firefox

this is the way the “pricing” text shows up for my product

but when browsing with IE

this is the way the “pricing” shows up

As you can see, IE wrap the text “$29.50” below the “Price:” I would like to have IE shows it up the way Firefox is doing it. Which part of the script shld i edit to achieve this? Thanks in advance
